I had this happen to me once before in Quinn's Aquarium (well, something similar anyway).
First, I know you said you logged onto Pogo, but I would make sure you are absolutely in your account. I say this because Pogo logged me out the other day & I freaked out when I saw the completely reset Merge Academy!
Second, if you are in your account and it is still like this...try logging onto your account on Incognito mode (or private mode, etc. depending on whatever browser you're using). When I did this previously and won a game, it fixed the issue back in my regular browser.
Here is a further troubleshooting guide if you need it. I hope your issue resolves soon.
