15b6 Compound Clip Transform applied to Clip below (Bug?)

Hello,
a CompoundClip with one UltraKeyer FusionClip inside has Transform set for Zoom, Position,Rotation,Pitch and Yaw.
The background plate on Track Video 1 gets the Transform settings of the CompundClip applied.
Moving the background plate to another point on the timeline without a clip on top, shows the footage without transform as expected. Only when putting it under the CompoundClip it receives the transform settings from that clip above.
Is this a bug or am I missing something?
Thanks,
