Lightroom Classic 8.1: Leica M10-P Huelight 3rd party camera profiles are no longer showing up

I use third party color profiles from Huelight (www.colorfidelity.com) for my cameras. I noticed that starting in LR Classic 8.1, there seems to be a bug in LR handling M10-P raw files. Third party camera profiles are no longer showing up. I have emailed Huelight and they too believe this is a LR bug. Hoping Adobe will look into this...
