I so here is the problem I'm having.

I had a pair of steel daggers set up in favorites for dual wielding. Right click and then left click the two stacked daggers and you have 2 of the same weapon on the same hotkey for right and left hands and the arrow icon says LR to represent that.

Well, I took those same two daggers and improved them to superior. Now when I try and put them back in favorites the number count disappears and it will only equip one of them with the hotkey. What's the deal?
