Socket Attatchment Collide with Environment

Hello,

I’m having a little trouble getting a crate which parents to my character’s socket to collide with the world while staying parented to the socket.
The best way for me to explain this is with some images:

Gameplay:

Right not I have the crate set the collision on all channels to Block but then once picked up set the pawn collision channel only to visible.
As you can see the crate doesn’t collide with anything at all once it is attatched to the socket. I need the crate to still collide with everything except the player
Cheers

I’ve checked the details of the crate during each stage.
The collision does set, it just fails to actually collide
