The problem with the display shield (The Elder Scrolls 5: Skyrim)

Hi all. Please help what could be the problem? I stopped displayed a shield of Blades, in the inventory it is it even possible to wear and it is fully operational, but it is not visible if to block the hero just holds an empty hand. Other boards appear fine,don't wear them because they have armor for 10 less. Maybe someone had this problem.Thanks in advance.
