Color profiles and Powerclip - X6

I am creating a CMYK document. After converting a reference photo to CMYK I imported it into my DRAW file. I will use that to pick colors.

The problem: the eyedropper tools work correctly capturing CMYK colors as long as it is not in a powerclip. If I place that image in a powerclip the eyedropper tool only sees RGB. 

Is there a setting somewhere that I need to make or am I stuck just working outside of the Powerclip? I have plenty of alternative ways to workaround this issue, just didn't know if this was a bug or something.

CORRECTION: It's not the Powerclip at all. It has to do with whether or not I have the layer locked. Unlocked = CMYK, locked=RGB. ???

Also, changing the Edit Across Layers setting seems to be a problem as well.
