Autostakkert Problem

Hello I posted this in Discussions - Software which I think may have been the wrong place to put it so I have also posted in this fourm

I have been capturing some avis of Jupiter last night using my DFK and I just tried a quick process in AutoStakkert but when I opened them most of the avis it looks like this below. The only thing I can see that is different is on the odd one where this doesn't happen the bayer is gbrg whereas on the ones where this strange effect is happening it says either mono or grbg. I captured them all in y800/y800. I don't know what has happened.

Has anyone seen this before?
