I'm sorry but I can't duplicate the problem and I don't know why that is happening to you.
I would try creating a new test deck, turn on spaced repetition, enter "new" mode, and see if button works. If so, maybe a solution would be to export your current deck with statistics and re-import back as a new deck.
If it doesn't work, did it ever work for you? You might try downloading Flashcards Deluxe Lite to see if a test works for you there. If so, maybe you can export your flashcards, delete the app, and reimport back (if you are comfortable doing so, so you don't loose your data.).
Is this iOS or Android?
