Weapon Equip / Unequip Animation Problem

Hi! I followed this tutorial (Unreal Engine 4 - Adding Equip Animation - YouTube) and I’m having a little trouble. Engine should play equip animation, then aim idle. Instead, my is first playing aim idle and then equip. Also when he unequips weapon, he still has it in his hand - it doesn’t attach to him. Here’s video : - YouTube
Any help please?
