I Don't know if anyone is still looking for a solution, but I found a quick fix on accident.
If you are using pathfinder and are suffering from the overlap or stacking effect... Add the 8Direction behavior to your enemy and set the speed, accel, and decel to the same values of the pathfainder behavior . Set default controls to no, and initial state enabled. Depending on the type of game you are making you can set the directions and angle accordingly.
For what ever reason this seems to work. With no teleporting.
