Wrong parameter. Sensitivity is a performance parameter, not a control parameter. Your Threshold setting is simply too low, and the module is interpreting vibration on the drumhead from the bass amp as intended activity. Just increase the Threshold until it stops, the only problem you'll run into is if the bass amp is so loud that it's causing the head to vibrate stronger than your own lower playing dynamics. This isn't likely, but just be aware of it.

Total overkill. With an acoustic trigger on a real head, it's not floor vibrations, it's outright airborne volume. The head is vibrating in sympathy with the bass guitar notes. Just increase the threshold.

I would do this first - it's exactly what the Threshold parameter is designed for. The vast majority of Roland false-triggering problems are caused by the factory-default thresholds being far too low for piezo-based triggers. For piezo-based systems, the Threshold should be set as high as possible without interfering with your playing. Start at zero, go up to 1 - check your playing, is it coming through OK? Yes - go up to 2, recheck etc etc. When you get to (EG) 10 and the module starts to drop your lightest ghost notes, then go back to 9, which will be the correct setting for your setup and playing style.
