Switching from optimized to raw clips when editing multicam

I'm using Resolve Studio 12.5 b3 and I've just decided to try and start doing my cuts in Resolve instead of Premiere. When I create a multicam clip and generate optimized media (I'm working with BMCC 2.5k and BMPCC footage) things work great. My footage plays smoothly and I'm able to edit just fine. My issue is when trying to switch back to my raw clips for the purpose of coloring. I click on Playback and uncheck "Use Optimized Media" which should get me back to my raw clips, right? Well, on the color page I have access to the raw controls but they don't do anything. The image doesn't change, my scopes don't move... Nothing. Is this a 12.5 beta bug? Or am I doing something wrong? All other color controls work just fine, just not the raw controls which makes me thing that I'm never switching back to my raw clips or something.
EDIT: I should add, sometime I don't even have access to the raw controls. And I just checked on 12.3 and have the same behavior.
