GMMK 2 RGB semi-unresponsive

After my most recent update to the Glorious Core software (1.0.33), the lighting seems to working oddly on my GMMK 2. I can swap between the various kinds of light configurations, but I can’t set it to a single color for any of them, and the Rate seems to be stuck at 100% even when I set it lower and save. Is there something I can do to fix this issue? An uninstall and reinstall of Glorious Core didn’t work to resolve it.
