MMA Last Played not syncing back to MMW

[MattTown]

Hi,
I use MMA as a player for my MMW library. I want the date that my songs were played in MMA to be synced back to MMW. That happens sometimes but generally not. For instance, I spent about 1 hour listening to songs on MMA and rating them for later use in MMW. When I synced the files back to MMW, all of the rating updates were synced but only the second half of the last played updates.
This has only become apparent a couple of days later so I can't recall an activity on the phone that might have delineated the first and second halves of the MMA listening session.
MMW version is 3155 and MMA version is 1251.
Cheers
Matt
