PROBLEM:
However, this does not fix the problem for me! I can load any other mod or no mod and the markers are shown fine. As soon as I load my mod, they are gone! I dont have any backup and I just worked about 2-3h non stop on it and I really dont want to redo everything! I also look through it with TES5Edit, but I couldnt find anything!But then again, what am I even looking for?
Please, anyone who knows how to fix that, please let me know!

PS: hitting M repeatedly and desperately does not help....
HOW TO FIX IT:
After playing around quite a while with CK and TES5Edit, I was able to fix the problem by deleting the Navigation Mesh Info Map with TES5Edit, then create an empty new esp with CK and merging the the esp where the dots arent shown with the empty esp.
Opening the merged esp and the dots are there again!
Maybe someone else has this problem in the future
