SAE and Furrynutz are PCs, not game consoles. I put them in the rule to show that you can have PCs in gamefule as well so when xboxes are online at the same time with PCs, the router can help manage traffic and still giving priority to the xboxes so they have good gaming experience while still providing internet to the PCs.
Just remove the xbox console rule you have at the top and your good to go.
