We had an 01 model with the wardrobe slide with the same issue. since that was about 15 or 16 years ago, i can't recall exactly but I seem to recall 2 adjustments at the motor - one for the inner stop and 1 for the outer stop. Your newer model could have a different model actuator, but I seem to recall 2 screws (slot or phillips I don't recall) but they were close together and would correct the issue you are having.
