Alesis QS8.2 Bank problem

First I need thhe rubber feet that attach to thhe bottom of the keyboard. I am missing two. Help with a source is appreciated. Second…This unit was purchased used and required some easy repair. I replaced the broken power switch and removed and replaced the 3v coin battery on the motherboard. the firsst four banks (preset1,2,3, and Gen Midi) all work properly but the user bank has no preset sounds in either program or mix mode. I can however create layers and splits and store to the user bank. Any thoughts on whats going on?

Any help is welcomed
