Control pedal for Beatbuddy turning on Aeros when I just want to roll the drums...why?

I’m not sure if this is the right place to ask if it isn’t please tell me…I use the Beat buddy/Aeros and Midi Maestro (in Aeros mode) for live performances. When I loop I like the bb to start the looper after count off. What I am finding though is that when I press the roll switch on the pedal it will intermittently start the loop playing even though I don’t want that. I figure it is a setting I don’t understand or something. Please advise.
