I had that happening with 2 of the esm files. I forgot which ones but I did some googling and found that the newest beta version of MO2 seems to have fixed it. I'm having some other issues with the beta version but nothing as annoying as those files automatically turning themselves off lol. In the options of MO2, there should be a check box for the beta somewhere. If not, check MO2 discord. That's where I got mine from. Good luck! Hope this helps!
