The other day I shot a match, it was unknown to me that they had not refreshed my division from my online change the night before. I asked to be changed from SS/M to Prod/Min, but the person handling the scores changed only the division to Prod and the Major PF remained, the app effectively took it and calculated my scores as Prod/Major, which is an illegal or inexistent combination.
I think a validation should be added to divisions like Prod and CO that are minor power factor by default to not allow major PF to be selected.
