It could also just be a lack of communication on their end. The last few trips I've taken, I've booked my ADRs, PSs, whatever right at the 90-180 mark (whever the soonest allowable date was), and about a month before my trips, I get an email saying how "happy wdw is that I'm coming soon, and would I like to enhance my trip further by dining in one of WDW's legendary restaurants"....obviously, they just sent the email without knowing that I actually already have ADRs made. but, it can't hurt to call and confirm, rather than risk going hungry!
