Thank you for posting about the flashcards. This is actually part of the spaced repetition system that the new flashcards use.
Your deck will be available for review again in the near future, but if you would like to study more right away, here are some steps you can take:
- Raise the Cards per Session and New Cards per Session limits in settings
- Add new cards to the deck
- Build new decks
We will be implementing a feature that notifies when a deck is due for review again soon, and are working on a new interface that will make the spaced repetition system easier to understand.
