Scoreboard please go away!

I have my jump key on the tab button in BF6 but every time I use it the scoreboard comes up. I have tried to change it but nothing seems to work. I want to move the scoreboard key I have tried to change the scoreboard to a different key but every time I hit the tab key to jump the scoreboard comes up also! I have tried a number of different keys but still when I hit the tab key the scoreboard shows up.
