Drum Kit not triggering sounds in Logic

I'm using a new Alesis Crimson II drum kit with Logic Pro X and Drum Kit Designer. The hi-hat (and occasionally other pads like the floor tom) will not trigger sound in Drum Kit Designer. I have tried remapping, but that didn't solve the issue and only caused me more confusion (simply assigning a new note didn't work). I'm not seeing a way to setup proper MIDI mapping within the drum kit module, so it seems it has to be done in Logic. I was using an older-cheaper drum kit for years before upgrading with no issues and no remapping needed. Been trying to solve this issue for months. This seems to be a common issue, but there doesn't seem to be any helpful solutions out there. Any advice?
