Thanks for reaching out. It looks like this is an artifact with the Raw Remove Noise - Strong model.

I documented this for my team and we will fix it when we update the Raw Remove Noise model in the next 1-2 months.

For now, I would recommend switching to the normal model which does not have this issue.

Thank you, I will give it a go.

and it worked! thanks. scott
