I'm only on frame 120, been studying 20/day, and using ANKI. I'm using the 6th edition book and when I was reviewing a few minutes ago 3 kanji came up in my review that I've never seen before; they were "rule," "current," and "queen."

Anyone know what I'm doing wrong?

So I'm just gonna toss out a few thoughts here.

It might be different in the 6th edition, but in my 4th edition 'rule' is frame 88, though that doesn't explain the other ones. :/

Are you certain you're using a 6th edition deck?

How do you tell anki which new cards to show you? Are you using the 'new cards/day' or the suspend-everything-then-unsuspend method (or something else)?
If it's the 'new cards/day' the order might be wrong, and if it's suspend/ususpend you could have just accidentally unsuspended them.

That's all I can think of, hope some of it will help.
