voyage planner crashes

When I right click on some routes I get the following message:
"Element with the same name already exists in the scope"

Then the program crashes.

Does anyone else have the same problem?

I have the same issue on both a Win 10 desktop machine and a Win 10 laptop.

I suspect there is something wrong in the route file I downloaded from my eS 127, but I need some hints on how to clean the file.
