The length of that roller pin is still worrying me. Given that the door can move forward/aft a tad, the locking bolt is very near the end edge of that roller pin.
That was my first observation also. The pin appears to barely reach to where the locking bolt is located. Given the (apparent) lightweight construction of this
door (composite?) it would not take much central outward flex, shortening the lateral distance between the guides, to clear them completely.
