I have something similar, under my reservations my tickets are showing but under the cards and magic bands section it says I have no tickets and need to link them. For a few weeks I kept getting a message pop up every time I logged on telling me about Magic Bands and FP+ and asking me to link my tickets even though they are already linked. It stopped happening a few days ago but now my tickets do not show up anywhere. I think that perhaps they are preparing the accounts for Magic Band customization as when I called saying my tickets were no longer showing and making sure everything was ok the CM said they were expecting the bands to be in use by at least all resort guests by November. Of course I took this with a pinch of salt but I do think they are preparing the MDE site for when the magic bands are rolled out.
