Logic Pro 8 Multi Instrument not banking properly

I copied my L7 environment over to L8 and hit my first really annoying snag.

I use my outboard JV1080 a lot for sketching, and normally I can select any one of 10 banks easily from the Arrange track parameter box.

However, in L8 I always get the same bank ( 11) though I've checked the 'Bank Select' in the JV1080 Environment object multiple instrument - it looks exactly as it did in L7.

Has anyone else noticed this behaviour?

If so, is there a fix?
