gotta say, it's almost impossible to read that image,
it's too small !
any chance of a bigger version?
i'd say check the clip's Alpha channel, although it looks (when i squint) to be correct : None / Ignore
check to see if the clip has any offline components.
i've had clips which *think* they connect to two instances of the same file,
one of which offline.
reconnecting (manually) fixed the issue
