Services in accessibility won't stay enabled

[HighfiveHeadache]

I sent my broken Samsung Galaxy S5(sm-g900t) into t-mobile and recieved my replacement, but with Marshmallow on it. Nothing but problems since.
This specific problem is with Clean Master. It requires permissions in the the accessibility menu to do a full clean. It was never a problem on Lollipop. Other program have requested it before as well. The problem is it won't stay enabled. I don't use the clean function very often, maybe once a week, but by that time it always asks me to enable Clean Master under Accessibility.
Is there any reason my phone would do this?

I cannot see why any "cleaner" app would need any options under "accessibility".
Which "clean master" app? Hopefully not Cheetah Mobile.

Sadly yes its Cheetah. For all its bloatedness, it has some features that are actually helpful.
Regardless of what or who it is, why would my OS continually disable a service I've enabled?

It happens on mine especially with Google screen search and glance plus app... I always need to set them up after a while.. my OS is Marshmallow
