inReach web UI won't let me edit routes

I have about 40 different routes stored in the inReach.garmin.com website maps. Most of them are editable, but some of the more recent imports are not and I don't know why. On some recent imports, clicking edit just lets me edit the route name and does not give me the drag points to adjust the route itself. But some older imports, imported using the same method, give me all the drag points and are completely editable. I have tried importing from gpx files and from courses stored in connect.garmin.com. Doesn't matter which route I go, I still can't edit newly imported routes. Any ideas?
