(roblox constraints) character not moving with parts

on a part im using align orientation/position, linear velocity and a plane contraint to move a part around. all the contraints are in the red box:

however in the video im moving the align position around and the character is not moving with the part. is there any way to fix this? because usually characters will stick to blocks under action by roblox constraints. heres a video to show you what i mean
