Is the END of the bolt/pin hitting the striker plate? If so and you have adjusted it all the way in and still have the problem, see if you can adust the plate away from the door. If the problem still exists, you could try to adjust the latch away from the jam, make sure the hinge side of the door is tight. One last thought is remove the pin and grind off about 1/8 inch.
I really doubt anyone would make an electric auto closing door. If they did, you would still have problems if the door/latch wasn't adjusted properly.
