You are not the only one. This happens to everyone. It is the traffic engine that VOXATC uses that is different than the default traffic or the addon traffic programs. I've tested this extensively with many different combinations of traffic addons and scenery. This is something that Tegywn would have to create a fix for.What I use is the FSX traffic setting at 50% and the VOXATC traffic at 0%. If you are patient on takeoff, fly properly, and keep an eye out when you land, there will not be any conflicts. AI planes still avoid you and go around like normal.
