MM3 not sending volume leveling info to ipod for some tracks

[tigers1122]

Im using MM3, Vista and a fifth gen. 80 gig ipod.

For some reason some of the tracks that are volume leveled in the library aren't showing that they are leveled on the ipod.

Is there a setting I need to change somewhere?

The tags of the tracks in the library show the data, but not on the ipod.

Thanks for any help you can provide.
