Reverse course and sampling

Yesterday I did this long training course:
https://connect.garmin.com/modern/course/330102256

Several weeks ago, I did it correctly. Yesterday, I tried to use "Do course in Reverse."

But I had a bad surprise:

- the course became sampled with very few points, losing details about crossroads

- losing notifications about the crossroads

Did you have a similar experience?

ps: next time I will reverse the course from Connect Web before uploading that to watch :(
