Packed Level Actors Strange Collision Behaviour

In this video, I place 4 vertical assets, rotate them flat, and merge them into a Packed Level Actor.

After scaling the PLA, the collision of the assets in the PLA no longer matches what is displayed in the collision view, and the behaviour is unexpected (floating in mid air).

Is this behaviour a bug? Or is scaling/rotating a Packed Level actor not recommended?

Yeah same here. Scaling a PLA causes strange collision behavior. Im making the scaling changes in the underlying level and then pushing that to the PLA. Kinda lame though
