midi track's mixer volume and pan controls are just dedicated to their midi channel volume (cc#7) and panning (cc#10) controllers.
so it might be case you're facing that either:
a. you have more than one midi track assigned to a same midi channel;
b. your midi clip files have some embedded cc#7 and cc#10 events in them;
c. something else i fail to ack.atm.
and yes, you're here invited to update to latest svn trunk (currently v0.5.7.25+), by all means ;)
