I can't get overrides to work on the Goal Line Normal FB Dive when I use it for two-point conversions. Any ideas why this might be?

I don't think the answer is fatigue. I've tried inserting a RB or WR from the bottom of the depth chart into the FB1 position, making sure it was somebody not already part of the play, but in the game it always defaults to the FB1 in my depth chart, even when the play is called in the first quarter.

I've gotten the same (failed) result in three different leagues.

To add to that: I can't override the TE positions with WR's on the goal line ppass play. The overrides don't even have players in those positions for me to swap out. They are blank!
