On the CyclOSM layer there is a crater/ basin here, but not in real life.
On the standard map there is no basin / crater and is correct.

The trail continues something like this. I have the exact trace recorded with my suunto watch, but I don't know how and if it is possible to import.

This basin is not correct. There is no such basin in that point

This hole is a mistake,there is no such hole here.
