5 pro cable snagging on QR pulley cover

Hi. I purchased a 5-pro from eBay.
It’s working well but I have a problem which I think is a basic fix.
The filament tube and cabling gets caught over the arm end with the QR code on when the head moves to the furthest point. I have strapped a pencil to it to stop it happening but I can’t help feeling it’s been routed incorrectly?
Any help is gratefully received!
Thanks
