Armory does not swap Sanctified item

Was using a build that did not have a sanctified item, specifically, a Rathma build.
I had an iron rose saved in an different armory build that is a sanctified item.
Swapped to this other build.
All items and gems swap except the shield I was wearing in the offhand (the same slot as the saved iron rose).

Was expecting the armory to swap in the sanctified item that I had saved.

EDIT: Additional step of pressing the armory swap button a second time swapped in the sanctified item as expected NOTE: Still a bug that needs fixing as I entered a GR with the wrong item mistakenly.

I think it’s because the items get swapped 1 at a time so, when it had to swap the off-hand, your character still had the other sanctified item equipped and the restrictions made it impossible for you to have 2 sanctified items equipped at the same time.
