When mine came out the same way I had to tap the set screw hole to a slightly larger size as it was striped when trying a new standard size set screw that came with the ropo door cylinder from Mac's, purchased a new oversized set screw from McMaster-Carr, used masking tape to hold the lock rod centered and reinstalled and put in the new set screw, all without taking the door apart.

Just looked the set screws I used were 10-32 X 5/8 allen, I ran a 10-32 tap in lock tube with cylinder out to go deep, my doors were 40 doors with the 37 hardware welded in the 40 doors for the window tracks.
