Production numbers are actually #1122A and #1122B while other two-part episode have production numbers like #416 & #417, #501 & #502, #311 & #312. That means it is one jumbo episode (11x22) for the season, but two for the production overall, causing the shift in overall episode numbers. That explanation fits with how producers have explained it, so that is the only correct way to handle it.
