The intervals for good and easy just started showing 1.1mo and hard at 15m on every single card I have already done. Even if I had last used good at 1 day. It is doing this for all cards in the deck. Before the good would be a couple days and easy would be a few more days. There are some cards I have got to have good at around 7 days before. But now all the cards are are showing this 1.1mo for good and easy, and 15m for hard.
I have not changed any of the settings, it just started doing this itself.
