After using Facebook AI Downloaded data and merging with streetmap data then fixing Validations JOSM does not register changes and cannot upload to streetmap using facebook data but erasing tags used by facebook data that are validated as errors.

What steps will reproduce the problem?

1. Using MapwithAI
2. Merging MapwithAI and OpenStreetMap data.
3. Fixing validation errors

What is the expected result? upload of alterations after merging

What happens instead? upload icon will not initiate

Maybe I don't know how to merge correctly, or its a genuine issue.

@AlPZz: How are you merging data? You should be using the command in the data menu, or its assigned shortcut. You really shouldn't be modifying the MapWithAI data layer (you can, if you want to, move buildings/roads to better locations before adding, but you should not be adding additional data to the layer).

Data -> MapWithAI: Add selected data is what you should be using.
