Wrong track names when exporting multiple route relations to gpx

[ggrab]

What steps will reproduce the problem?

1. Download two route relations with the same starting point, e.g., "377893,1291880" (hiking routes)
2. Select both relations in the relations dialogue and right-click "Export GPX file starting from first member"

What is the expected result?

The tracks (<trk>) in the generated gpx file have the same name as the route relations, i.e. "Wanderweg 5" and "Wanderweg 6" in the example above.

What happens instead?

The tracks (<trk>) in the generated gpx file have the names "Wanderweg 6 #1" and "Wanderweg 6 #2".

Please provide any additional information below. Attach a screenshot if possible.

If the routes do not have the same starting point, this does not happen, and the names of the tracks (<trk>) are as expected.
