Can you please investigate why we cannot use the permissions against folders in OTBI ?

Summary

Why we cannot use the permissions against folders in OTBI ?  what happens now is: when we got enough access, we can set up a specific permission at a certain level, but the next day, we will find out that it has been completely erased and replaced by some common rules that applies from somewhere else. It looks like every night, something runs and replaces folders permissions.
Can anyone please help on it.

Thanks!
