Auto bracketing mode disappeared after the 1.58 update

[NN635257672892292655UL]

Hi there,

I asked the certified mamiya/P1 dealer in Paris to do the upgrade of my 645df's firmware and now i don't have any access to the auto bracketing mode.
What can i do ? A downgrade of the firmware ?

I should have been more precise. This is the RP mode that is no more available.
When i turn the front dial to ON there is no more the options to select the number in units.
If i select the C mode and start to shoot an error message appears.

Ok phase one answer me.
They disable that function to fix a stability conflict.
