The issue is that your midi files contain panning information so that is over-riding whatever setting changes you make in Logic.
To fix this you will need to look in the Events List on the right hand side of Logic's main screen
Select each midi region... and Choose List and then make sure the Events tab is highlighted.
Press the 'selection' buttons so everything but Controller are dark in color.
Now look through the list shown for controller events that will affect panning....
Pan is CC (Controller) #10
Delete these entries by clicking on them and pressing the delete key and then test....
Once you have done all the tracks.. resave project under a new name...
The section on the event list in the guide, can be found here...

Your MIDI file will contain Panning controls, which are MIDI Controller 10, so if you select one of the MIDI parts and open up the browser on the right hand side (the Media area and Audio Bin and so on..) under 'Lists', you'll see the Event List. That should show you the type number 10 against some of the entries there. You can use selection functions in the Event List to isolate events of one particular kind, I can only leave you to have a go really - if you narrow it down, you can just see controller number 10 values, so you can adjust or delete the entries.
Edit - somebody beat me to it, he he...
