How to reequip your other shields after purchasing Uplay stuff?

In Assassin's creed brotherhood, I've purchased Uplay stuff, like the shield of Altair, and Ezio's young Florence custom, and others. Now the thing is I can't wear the shield of Romulus no more, when I stand next to it in the Tiber hideout and reequip it, it do reequip and Romulus shields disappears of the stand but it does not show on ezio’s body, he does not wear it he keeps wearing the Altair shield?? Any ideas?? Thnx in advance..
