Landscape material resets after saving

I have a problem where my landscape material’s opacity mask doesn’t work until I modify the landscape (example: sculping), and it resets when I save it or rebuild it

I’ve narrowed down to Nanite, the mask material doesn’t get applied or updated until the landscape gets modified, however it goes away when rebuilding it, how can I keep the mask that’s applied to the Nanite landscape?

I found that disabling nanite fixes the problem, I’m not sure why opacity mask doesn’t work in nanite
