Unseen words marked as learned/strengthened

Over in German, I was going through numbers again for practice, and at the end it said I had strengthened the word "Dreiviertel". It says I have seen the word three times, and have effectively mastered it, giving me all four segments on the mastery-o-meter (or whatever it is called :) ). I am absolutely sure that I did not see that word as I went through this section this time, and am pretty sure I have never seen that word in DuoLingo practice.

I was under the impression that other words have been incorrectly credited to me as having been seen several times and at least partially learned in the past, but was never quite sure. But I know that "Dreiviertel" is a word that was never presented to me.

I'm seeing the same issue. The Words Strengthened page shows words I have not yet seen within Duolingo!

Same here. I've just re-visited "Dates and Time" in German and DuoLingo said I had strengthened words I don't even remember seeing during that session, like "Veranstaltungskalender" and "Öffnungszeiten".


I just noticed this as well. I just finished repeating a lesson and a word I never learned appeared as fully strengthened. I now notice that I have several of those words "learned"...

I'm pretty sure the word in question was in one of the "mark the correct translations" type of questions, but those questions shouldn't strengthen words that are not part of the correct translation!
