That's correct. You must wait until her 60-day window opens.
Her packaged tickets are not active. They become active on the day of her check-in at the resort. It's the "package" that allows the FP booking window to open - FPs can be booked for her only when her window opens.
So it seems that buying tickets with an agency like UC is better than buying them with a package... Not only cost wise but if you are going with family and arriving on different dates. Thanks!!

.. we will have something booked for early/late afternoon
