I made another profile today and and learned a couple of things.
Before I started I changed a setting in Windows, I had set the theme to High Contrast Black and turned that off and that fixed the typing issue. Rig Manager is not able to handle that theme, (some programs can and some can't).
After that I re-profiled the same amp I did yesterday but this time RM was not running and I did it all from the Rack unit. Everything went fine and the Kemper picked up my name as the Amp Author. So, I would say the profiling assistant in RM has a problem reading that info from the Rack unit.
To clarify, I am using RM 3.5.27 and Kemper OS 10.2.3.53270 on a Windows 10 system w/ all recent updates.
