Logic - Midi Track 16 Problem!, Midi track 16 changes synth mode Options

[markwhite]

I am using Logic Express 6 on my G5 with a audiophile 24.96 soundcard and Roland XP30 synth. I have always used a template environment for the XP30 which is good but when I select Midi Tr. 16 on the arrange window it triggers my XP30 from perform/part mode to Layer mode which I dont want.

This only happens on tr 16. How can I change this or what settings should I be checking on this track. I have checked that all the program numbers and everything else matches with the other tracks (on left hand side box in arrange and environment)

Any advice would be great!
