Custom network manager ui

so ive made a custom network manager, and a new ui menu prefab, and have linked them together. now hosting works, joining not yet, but when i build the game, and run it in the editor and in another window, the default network gui comes up in the build one, and not in the editor one. i first disabled the gui, and then removed it completely from the game object with the network manager. it is still appearing in the build

ignore, i was building the wrong scene…
how do i function everyday
