D2X Bank problem

I recently bought a D2X. I am having trouble with the 4 Banks. When I adjust Bank A for example the other three Banks change to the same setting as A. When I adjust Bank D, Bank A changes automatically to the setting I just put on Bank D.

I have looked at the Manual and can't seem to find solution.

On my D200 I have no trouble, since after settings are made you can cick on Done, but I cant seem to find that option In the D2X.

Any info will be helpful,
