overlapping snap areas - better snap tool

In Better Snap Tool I created a new snap area - basically a window on the bottom left 1/8th of the screen. no problem in creating it, or so I thought. If I try to drag a window there to snap, on the way I see 3 phantom outlines of windows - the little window in the center, the right half screen, and the new snap area I created. I can't figure out where to drop the window i'm dragging to activate the new snap area - have tried everything.
