Groove Agent 5 - Drum Patterns Not Playing Correctly

I’m experiencing an issue with Groove Agent 5 where drum patterns are not playing correctly. When I load a drum pattern and hit play, some of the drum elements seem to be missing or are not triggering as expected. This occurs both in the standalone version and when using Groove Agent as a VST plugin within Cubase. I’ve checked my MIDI setup, and everything seems fine on that end. Could you please provide assistance in resolving this playback issue?
