Import issue on Cubase 6 upgrade

I have a track created in cubase studio 4. 9 vocal tracs all panned in different directions for the most part. When I open the track in Cubase 6 all the panned tracks display incorrectly in the mixer bar with the meters however everything seems to sound fine. All pans show tthe meters as if they are panned to the right even if it sais they are panned to the left and so on. Any fix for this?

Thanks!
