Armor wont leave my inventory

Armor won't leave my inventory.  I'm a beta tester for minecraft pe  on my phone so I'm experimenting in creative and I was putting  some armor on some armor stands. The boots won't leave my inventory even if I try to put it on my character they won't go on either or go back in the item category where I got it from. Help would be appreciated with resolving this issue. Warmest regards,
