Alpha Key Misalignment with Decklink Duo?

Trying to isolate an issue I’ve been having for a while now, any alpha keying coming from propresenter 7 through my decklink duo 2 and into my ATEM TV Studio HD has this same line going across the top. My guess would be that the key and fill are somehow off, but between the ATEM and ProPresenter there aren’t any changes made that would affect that. Any ideas?

Pics taken on 2 separate monitor feeds which are keyed, and a screenshot of my windowed ProP7 feed.
