How can I use all four D-Pad secondary weapon slots in Darksiders?

Question

I am currently playing Darksiders and the down slot in the D-Pad has somehow been assigned to the gauntlet. I want to assign the horn to the down slot in the D-pad but when I try to do it, the slot is simply blocked. I can't 'move' the item to the slot below, only to the top three slots shown.

This is what it looks like while playing. The gauntlet has fixed itself in the bottom slot and I cannot remove it.

Is there a way to reset or clear these assignments?

Answer 1

It is not possible to reassign the bottom slot.
This slot will either hold the Gauntlet or the Scythe.
The bottom slot will hold what is currently not equipped.
