I think this may in fact be two bugs: I had a puzzle yesterday which I was sure I'd had before, and quite recently. Anyway I got it right, and turned my PC off. This morning I opened up Training on the app (on my phone) and guess which puzzle it was?
At first it seemed from the webpage that I'd gained points for this, but when I did another puzzle and got it right, the rating gain looked right, although it still said I had solved two puzzles.
