This is a recent but not new issue. The workaround I posted in another thread was to make sure you start by viewing/modifying a reservation that is not at the top of your list and is preferably a cash (not points) reservation. After that things seem to work properly. I frankly don't know what I'd do with only one or two award reservations. Fortunately I have a Park 'n' Fly cash booking part way down the first page of reservations that clears the issue every time. It would be worth making a distant future cash reservation just to have this option.
