Third Person Camera Movement Bug

Hello everybody,
got an strange camera bug over here.

My third person camera glitches around soon as i jump on the right side of objects.
Like you can see in the video it only happens on the right sides of staticmeshes.

Already played around with the collisionmeshes, but that dosent seems to be the problem.
Iam using an third person template for my “sidescroller” project with a disabled camera rotation.

Would realy apreciate if someone could give me a hand on that one.

Here’s a video:
