Incorrect calculation of the remaining mileage if the route deviates!

Unfortunately, this bug has always existed in LM4... I've reported it several times already – and I've always received good advice on what to set where and how to fix the problem, but unfortunately, none of it helped!

The problem:

If the route traveled deviates from a planned route – e.g., due to a shortcut – and is then "returned to" again, there are no more navigation announcements after this deviation, and the remaining kilometers to the destination are calculated incorrectly!

These may even be more than less...

Attached are images and gpx-files of the planned and driven routes at the "shortcut" point, as well as the log file (although I couldn't find anything there).

If there is a setting that permanently resolves this behavior for all existing and future routes, please let me know what I need to set where and how. Otherwise, it's about time to finally fix this problem!
