Hey.
Monterey 12.3.1 (21E258)
using the Raw power app I don’t have any issues, it aways selects the Raw file.
It is probably just the OCD in me but as you know once you edit it in Raw Power it locks it to the Raw file in photos, which is all fine.
But… in photos the image still says JPEG + RAW instead of RAW + JPEG and of you can use the switch to raw as it is locked.
Only a small thing but it just helps to know what file you are looking at.
