I've noticed the latest PS Beta release (26.5) appears to have a bug in the Info Panel. I have it set to display Actual Color as RGB and Lab Colour, Lab is displayed as CMYK and if you select CMYK you get RGB!. Its certainly an issue on the current Beta release using Windows and it may have been an issue with the previous release which I didn't use as I'd been away recently. It doesn't show as an issue in the current PS (26.3) release.
Thanks
John
