Basically what the title says. One example: I just reviewed 世の中 and got it wrong (went back to Apprentice). After that, I was shown this summary:
As you can see, there’s no 世の中 there. I also did the review for the kanji 後 (got it right), as you can see in the items that got guru’d (red mark). This is definitely happening with other items that I get wrong. Not sure if it happens on the ones I get right.
This has been happening for like 1+ week, but I thought it was a problem on the Android app since I’ve always done my stuff through there. However, this also seems to be happening on the website.
Hope any of you guys or staff member(s) can clarify me about this. Thanks!
