Can't copy head accessory in CAS

In CAS it is impossible to copy head accessories. If I use any other category I can easily copy an item to all outfits , except for head categories. This is true for the base game bow as well as for the enchanted by nature items. I would like to use this feature , especially for the horns and antlers to be present on all outfits .  

The tooltip says: Currently nothing from the hat category is applied. (free translation from Dutch)
