BUG: Key turns purple and shows mask
I have both a lumetri effect and an ultra key effect on shots, along with a mask to limit the amount of keying. When I do a copy then paste attributes, I get this funny result. If I close the sequence and re-open it, it's fine. And surprisingly, the renders have been fine. (fingers crossed going forward).

I'm also having this problem. I also have an ultra key layer, lumetri effect and a mask to limit keying. My problem does not go away by closing the sequence. I also get the error on export.
