Networking Issue

I created a main menu for my multiplayer game. I want the client and server to work completely independently in the Main menu because they obviously haven’t connected to each other yet. But the problem im having is that the client is able to change the resolution size for the server but not for himself. So they are not currently independent. Did i mess something up here or am i going about it incorrectly?
Side issue, the server is getting the HUD from ingame despite the remove all widgets, whereas the client it works fine(it is removed)
