Power window incorrectly follows position in edit mode

I'm new to this forum but I hope someone can help me with an issue that I haven't experienced before in all my years using DaVinci Resolve.

I use a power window and qualifier to remove my green screen. Now when going to edit mode, to have my subject move into view, I use position x in the transform section. But when doing so the power window moves faster than the subject!

Please refer to my screen recording over here:

Any help would be greatly appreciated! (I'm in version 16.2.8.005)

Cheers,
Maurice

Update: I found that if I turn the clip upright in edit mode using the inspector instead of using clip attributes in the media pool, I don’t have this problem. Surely it must be some kind of glitch then!

Turn the clip upright?

Upright as in rotate 90 degrees!
