BetterSnapTool - Can't setup snap for multiple monitors. Please help

Hi there. I have a question using betterSnapTool. I have three monitors in my setup. When I setup a new snap area, the active window keeps defaulting to my left monitor..... How do you "move" the active window? I'm not able to click and drag it to the monitor I want it to show up on. I've tried creating the snap area on the monitor I want it to be on and it doesn't help at all. I've even tried changing my main monitor to be the monitor I want on the snap area.
