That's absolutely a good way to settle it, Indeed we get the solution from AH,
However we wanna figure out what's root cause lead to this situation?
Long-term hoist operation? or issue remain since delivery?
Actually we compare initial adjustment after delivery, Exact position It's almost same,
Only difference is door will become hard to lock in place after period of operation,
Did you try to add an belt-handle at inner side of sliding door to facilitate this situation? or grind off tip of dowel pin to become sharper in order to easy alignment?
