Tiled Mutlires Level don't work on Quest build

Hey we have a problem with our current Oculus Quest game. Everything runs well except the Tiled Multires Level doesn't.
I set it in the Awake of my VRManager. Also tried the Start function.

OVRManager.tiledMultiResLevel = this.tiledMultiresLevel;



In the Build it say that the TML is on for this devices and set correctly. But when i look at the edge of the screen, it is still fullres...

Some ideas?
