Okay, not sure why this happens but here is the solution. Took me forever to figure out. So go ahead and make a brand new library. Then go ahead and Import one of the raw red files newly into this library. Try changes the red raw settings for this file now, this should work. So now go back and copy the old timeline and paste it in this new one. Then close the old library, then just relink the media from the raw files and you should be good to go. It’s something to do with a corrupt library.
