Technical Can't equip hands and feet

[Roguelock]

Hi, the game doesn't let me equip hands and feet, Relentless Gladiator's Scaled Gauntlets and Graves of the 7th Legion respectively. The game say that: "You cannot equip more than one of those".
Even if i take off my other feet and gloves it doesn't let me, i tryed to unstuck the character but it doesn't matter.
Pls help me solve this problem, ty.

Make sure you don't have Unique gems in sockets of those items.
