snap areas moved to 2nd screen

Hello everyone,

I use BetterTouchTool for snap areas only so I am not very familiar with the rest of the tool. I sometimes use an external monitor and for some reason, the snap areas (where you drag a window to) have disappeared from my laptop and I see them only when I attach the external monitor.

What did I do to make that happen, and how can I get them back? Can someone can point me in the right direction?

Thanks in advance.
