Wondrous Tails bugged? Same book for 3 straight weeks?

So I was someone who didn't turn in their previous book prior to DT just in case I wanted the extra half level. This was from "a few weeks ago".

Then I got the next book for the other prior week, and it was exactly the same. I turned in that next book yesterday, and forgot to pick up the one from "last week", so now I'm on the current week and it is still EXACTLY THE SAME.

The last 3 books I've done have had all of the same entries for what to do. That can't be normal right? Is this bugged? I've been playing the game for years and I've never seen it do the exact same challenges 3 straight weeks.
