Attached static mesh doesn't move with Anim Montage

They’re not blended at all yet. I wanted to solve this problem first. Right now when you play the anim montage for the attack the blend space for walking just stops playing, and you slide (As if you were doing the anim stationary). The static mesh/weapon just only stays attached to the hand if you play the anim montage while moving, other wise if you do it while actually standing still it’ll float in space before reattaching when the anim finishes playing.
