You probably didn't set the drive select jumpers correctly.
If anyone is interested, the circuit for the switches is very simple.
When I made up a distribution card to use with an external drive box (in
lieu of an M9058) I drew it out and made some PCBs. You can find the
relevant schematics, descriptions, and some PCB layouts at

Specifically, the switches schematic is at
