Need help fast. Navmesh project settings wont save

I have to turn in my project at midnight today. When I run standalone my navmesh settings are on dynamic. Every time i reopen the project, the navmesh is on dynamic. I keep trying to set it to static and save, but it wont ever save.

Same problem here, but for me in nav settings “can be main nav data” is not saved after i close and restart unreal, using 4.25
