Stack of Tomes keeps floating, can't pick the item

It seems there’s a bug when I tried to pick the Stack of Tomes that I placed above the medium cupboard. The only thing I pick is the medium cupboard itself while the Stack of Tomes keeps floating without any command to pick the item. I have tried to relog in and nothing change (and yes, it’s my character, clipping below the Stack of Tomes as I tried to find the command to pick it up).
