The MIDI log shows that you're receiving a MIDI CC message on every channel. If you're responding to all those, you would get 16 actions for each button press. You can either change the Blueboard settings to only send on one channel, or in BandHelper, change Settings > Remote Control > MIDI Input Channel to a single channel. You can also look at the remote control status window (foot switch icon in the top toolbar) to see which actions are actually getting triggered by these messages.
