PR4444 requires render?

I received a PR4444 export from Resolve (on a mac based computer) and naturally I was expecting that I would be able to just pop into FCP7 and not have any render bar. Unfortunately, I end up with a green render bar, even if I let FCP7 choose the sequence settings based on the clip.

This is adding hours of time to my renders (long file) and I can't figure out how not to get a green bar.

The clip is pretty standard
1920x1080, 23.976, PR4444, PAR square, 48khz audio

My sequence settings match this but still that darn render bar, any ideas?

Solved - Alpha was set to white, needs to be set to ignore.
