Quite easy to adjust these are but I think you have more problems with the hinges, the top hinge/door has fallen and leaning to the left, the bottom hinge/door has pushed the opposite way, this is purely with the weight of the door. The bottom hinge pin is coming out which won't help, needs knocking back down. Open the door and look behind each hinge and you should see 2 allen headed bolts on each hinge, turning these left to right moves the hinge pin sideways and thus the door goes with it, these bolts only turn left to right by 180° so you have limited lateral movement. I think your main issue is with the black bushes within the hinges have worn allowing the door to fall, looks like it's a fairly older door and no doubt had some use so adjustment may be futile, it may need hinges but are readily available, ERA challenger composite door hinges
