Tracks keep loading unwanted Drum Map

Hi all,

I recently created a drum map that I’m using for my drum track.
However, Cubase keeps loading this drum map into other tracks without being requested to do so.
There is no obvious trigger for this, it seems to happen randomly (every 4-5 minutes).

The problem is super annoying as the unwanted drum map keeps messing with the melodies in my instrument tracks.

Any suggestions?

Cheers
Beverly
