Reply to Going from Gratification to Deckalized

Hey guys, I am pretty sure I am just dumb, but I am trying to get the Deckalized mapping to work on my MF, but I previously had the Instant Gratification mapping on there, do I just need to take it out of four banks mode for it to work?

I try and take it out of 4 banks mode and press the 5th button when in setup mode and no option comes up, just goes back to being a midifighter, makes no sense.
