Issue with online reservations?

[Kate'sDad]

I am going in Early December. I already have many reservations (in some cases multiple options so I can deal with any possible changes to what days I will be in what park). I am trying to switch a few things around and no matter what day, what restaurant when I try to book I get this below. Is there some maximum you can have on number of reservations for a given week? I am not trying to book 2 restaurants in the same time window.

Weird. Was able to do it with the app.
