Solved Remove admin from default Oxide group? (all players in default)

Using better chat and i have orange [title] black [nickname] and orange [message text] and white text for default members. When rejoin i am added again to default group and my messages are white. I have to remove myself form default group to fix this. Then if i add stema group plugin and its worse. I have to remove 2 groups. Ideas how to block user (me) from choosen group.
Ex. When next time join i do not wantto be autoadded to default oxide group.
