Thanks for the pic. In the wall intersection area, you need to manually override the cleanup radii to 0, not 10"+-. A picture is worth a 1000 right?
In this image, you see the endpoints for three walls: the horizontal, vertical and 45. Notice that the Horizontal and 45 are connected, while the vertical is not. However, they are only off by a couple inches. The other wall, is away from this main point by over 5 inches. The cleanup radii on one or more of these was nearly 10". This is where the problem is and why I drew the circle. The connected walls are cleaning up everything within 10". This includes that offshot wall. When this happens, ADT thinks something is not right and can't figure out how to clean your walls correctly, thus goes into red circle overload. By overriding all the cleanups to 0", or at least something smaller than 4", your walls will cleanup correctly.
