Grooves triggering Fill Ins when moved to composition grid

Since upgrading to Cubase 12, and purchasing full version Groove Agent 5, I am finding that any groove I move over, on replay from the composition grid( not sure correct name of window) the groove triggers fill ins on the Groove Agent that were not part of the pattern. I have tried uninstalling Groove Agent and reinstall. Not changed. Any suggestions? ( BTW, happens even when Not Connected midi selected.)

I think I found the problem. for some reason the "use pattern MIDI ports for Pattern Pads) was selected and the solution has been to change the MIDI channel from 1 to 15 or other… not how this became a default setting to trigger pads though… any suggestions?
