Just checked and I have the same thing. And my RUC wait list disappeared.

Actually, when you follow the 'manage' link it goes to a new menu when one can physically request upgrades, for each segment of a flight, or all of them at once. Not sure yet if this differentiate medallion from RUC.
I called the diamond line and she said everything looks good on their end in my itinerary (same upgrade requests as before) but they are making changes that will take until Saturday but did not know what these changes are.
