Same here with my new Audya 4 arranger- 41 B already installed when purchased

I usually save my registrations as a song name on my Audya 4 arranger and I trigger the module with a 13 note floorboard and play guitar live.
Anyone experience the following problem with Slider settings not saving on registrations in the Audya..
Every time I go to save my reg settings I do the following:

press save--then press button for Section 1/6 page 1 and 2,and select all the options by activating all the blue dots beside each option ie slider, midi, utility etc and then save, The reason I save all is that no one can tell me which one shoud or should not be selected. Actually I leave out one -Arabic -as i presume its not relevant to me. I then get a window saying FILE already exists-enter to overwrite: and i duly overwrite the old setting with the new one but keeping the name of the Registration the same.
Anyway it doesn't seem to matter what i save as every time I go back to my regs and play them back the sound booms out through my speakers and its obvious that Slider settings are not saving at all.
Anyone know where i am going wrong?
Any help is greatly appreciated as usual.

If this is a bug then its a serious one !! Especially for A4 arranger users who probably have their hands full playing guitar already and cannot reach the unit to reduce the levels as quickly as a keyboard player could.

I use key start all the time so have no way of knowing that the registration
I play is going to blast out of the speakers and deafen both myself and the audience
