This is just because favorite counts are cached. You can always manually change the page number in the URL, or the cache should expire after a day.

Just minutes ago, I was slightly startled by the same problem, thinking, "Oh no, maybe I have a favorites quota as a beginner."
Fortunately enough, I had the patience to look around, and the information needed was rather easy to find. Thanks for this thread!
If you only have a single page of favorites cached, what you need to add to the URI is, "&page=2".
Actually this has been asked several times before (cf. forum #20903, forum #16203). I wonder if this should be included in a sticky or a help file somewhere? (Though who knows if that would help...)
