Open several gpx tracks(gpx files with markers) 2. Merge markers into one layer. Merge gpx files into one layer. 3. Delete merged layer when unneeded. ==== What is the expected result? Successful deletion of unneeded layer ==== What happens instead? ""Report bug"" dialog ==== Please provide any additional information below. Attach a screenshot if possible. I think the same happened yesterday, but with combined(merged)**gpx** layers. Today it happened with combined **markers**. {{{ Relative:URL: ^/trunk Repository:UUID: 0c6e7542-c601-0410-84e7-c038aed88b3b Last:Changed Date: 2026-08-11 15:36:21 +0200 (Tue, 11 Aug 2026) Revision:19613 Build-Date:2026-08-12 01:30:51 URL:https://josm.openstreetmap.de/svn/trunk Identification: JOSM/1.5 (19613 en) Linux Debian GNU/Linux 12 (bookworm) Memory Usage: 1536 MB / 1536 MB (1296 MB allocated, but free) Java version: 26.0.2+13, BellSoft, OpenJDK 64-Bit Server VM Look and Feel: com.sun.java.swing.plaf.motif.MotifLookAndFeel Screen: :0.0 1024x768x[Multi depth]@75Hz (scaling 1.00×1.00) Maximum Screen Size: 1024×768 Best cursor sizes: 16×16→16×16, 32×32→32×32 Environment variable LANG: en_US.UTF-8 System property file.encoding: UTF-8 System property sun.jnu.encoding: UTF-8 Locale info: en_US Numbers with default locale: 1234567890 -> 1234567890 Desktop environment: LXDE libcommons-compress-java: libcommons-compress-java:all-1.22-1 libcommons-logging-java: libcommons-logging-java:all-1.2-3 fonts-noto: fonts-noto:all-20201225-1 VM arguments: [--module-path=/usr/share/openjfx/lib, --add-modules=java.scripting,java.sql,javafx.controls,javafx.media,javafx.swing,javafx.web, -Djosm.restart=true, -Djava.net.useSystemProxies=true, -XX:MaxRAMPercentage=75.0, --add-exports=java.base/sun.security.action=ALL-UNNAMED, --add-exports=java.desktop/com.sun.imageio.plugins.jpeg=ALL-UNNAMED, --add-exports=java.desktop/com.sun.imageio.spi=ALL-UNNAMED] Dataset consistency test: No problems found Plugins: + CADTools (23) + FastDraw (36503) + ImageWayPoint (36483) + JOSM.Missing.Tools (1.0.0-1-g417d579) + MultiLineToolbar (1767556793) + OpeningHoursEditor (36493) + PerpendicularWayFromNode (1.0.0) + Review.Changes (1.1.1) + SimplifyArea (36503) + adaptive-simplifier (2.8.0) + apache-commons (36483) + apache-http (36483) + buildings_tools (36503) + comfort0 (36483) + conflation (280) + contourmerge (v0.2.3) + ejml (36483) + geotools (36483) + gpsblam (36483) + gridify (61) + jackson (36502) + jaxb (36483) + jna (36483) + jts (36483) + merge-overlap (36483) + opendata (36503) + osm-obj-info (72) + reverter (36503) + sidewalks (71) + undelete (36503) + utilsplugin2 (36503) + waydownloader (36483) + wikipedia (448) + zoomlevel (0.1.0) Tagging presets: + https://josm.openstreetmap.de/josmfile?page=Presets/Addr2&zip=1 + https://josm.openstreetmap.de/josmfile?page=Presets/BuildingPreset&zip=1 + https://josm.openstreetmap.de/josmfile?page=Presets/Crafts&zip=1 + https://cdn.jsdelivr.net/npm/name-suggestion-index@latest/dist/presets/nsi-josm-presets.min.xml + https://josm.openstreetmap.de/josmfile?page=Presets/NewTags&zip=1 + https://josm.openstreetmap.de/josmfile?page=Presets/OneClick&zip=1 + https://josm.openstreetmap.de/josmfile?page=Presets/ParcelLockers&zip=1 + https://josm.openstreetmap.de/josmfile?page=Presets/Playground_Equipment&zip=1 + https://josm.openstreetmap.de/josmfile?page=Presets/Simple_Indoor_Tagging&zip=1 + https://osmtools.de/josm/steps.xml + https://josm.openstreetmap.de/josmfile?page=Presets/ParkingLanes&zip=1 + https://josm.openstreetmap.de/josmfile?page=Presets/LaneAttributes&zip=1 + https://josm.openstreetmap.de/josmfile?page=Presets/PublicTransportOneClick&zip=1 + https://josm.openstreetmap.de/josmfile?page=Presets/Quick-highways&zip=1 + https://josm.openstreetmap.de/josmfile?page=Presets/CommonKeyboardShortcuts&zip=1 + https://josm.openstreetmap.de/josmfile?page=Presets/FitnessStationEquipment&zip=1 + https://josm.openstreetmap.de/josmfile?page=Presets/NewParkingFeatures&zip=1 + https://josm.openstreetmap.de/josmfile?page=Presets/StreetCabinet&zip=1 + https://josm.openstreetmap.de/josmfile?page=Presets/Quick-buildings&zip=1 Map paint styles: -
