Combining 2 clips into new fusion clip results in blank clip

From the edit tab, I am selecting two clips with a few frames overlapping, and selecting "new fusion clip". This makes a single combined fusion clip as expected, but for some reason the first clip no longer displays. It just becomes a black frame, both in the edit tab, and inside the fusion tab. The second clip does display, but the first one seems to be just... gone?
Has anyone encountered this?
Edit: I'm getting the following warning messages in the log.. Seems like a bug?
