Ultra Dynamic Sky lens flare not working on playmode

Hey,
There is indeed a Pawn spawning (from ZED Camera Plugin - StereoLabs) with some PP settings.
I change the settings of the lens flare in the Ultra Dynamic Sky BP and can see the changes before I hit play button, I removed every other Post Process Volume in the scene.
I disabled the lens flare effect in this pawn but doesn’t change.

I can see my UDS lens flare in the pawn preview during playtime (see attached picture), so they didn’t get overwritten I guess ?
