Problem on mobile app

[WinAR6]

Okay, so I have the Duolingo app on my iPod, and earlier when I was practicing Swedish on it, I noticed something. When I was doing new lessons, the app was highlighting simple, easy words like ater and tidning, which are words I learned a long ago on my tree. I noticed the same thing happening to words like mangi and legge on my Italian lessons too. It's not really a huge problem, but it's annoying because for a second I think it's a new word, but its not. Does anyone else have this problem, or is it just me?

I noticed that the Spanish-English tree was recently adjusted and new lessons were added to skills. I already knew all the words that were introduced, but I assumed that I had just learned them elsewhere. It's possible that the reshuffling meant that words were wrongly classified as "new" when they shouldn't have been.

Anyway, I wonder if something similar has happened with the English-to-Swedish and Italian trees?
