Ok, I got the problem solved with color class on my desktop.  On my laptop however I can't get it to work.  I have the same settings as described in the manual and still no luck.  When I update color class in lightroom it is recognized in pm, but not the other way around.  When I tell LR to read the new metadata, it doesn't appear to be reading it.  I look on the LR metadata display and it still shows the old Label and not the new ones I created to match LR.
Yes, I tried reverting in PM and deleting xmp/iptc data, but that didn't work.  Any suggestions?
laptop has 20.4.11 and PM 4.6.1
Thanks
