BTT behaviour changed after moving to a new MB Pro

I first bought BTT on my previous MB Pro with Touchbar. I've recently moved to a brand new MB Pro, again with touch bar. I used Apple's Migration Assistant to migrate all my applications, settings & data. Strangely enough something has changed with regards to BTT Touchbar behaviour: everytime I switch apps now, the BTT Touchbar shows itself, which it didn't do on my previous MB Pro. There it would show itself automatically only when waking up, which was how I liked it. What do I need to change in my setup to stop that automatic app switching activation?

Thanks & cheers --Mike
