You are right – its a bug. Pitch1 is connected to all the shifters, while pitch2-4 control out are unconnected. Presumably pitch1 should be connected to pitchshift1, pitch2 to pitchshift2, etc.
I've attached a fixed version – you will need to change it to .sig, and then use Vsig to send it to the unit. Or, alternatively, you can make the changes with the front panel ptach editor.
