Duo Spanish mistake/confusion?

A recent Duo Spanish lesson taught me "liquido" for "liquid". As in "add more liquid to the stew". But in the flashcards, it gives me the English "net" and expects me to answer "liquido". What? Is this a financial meaning? (as in "net assets" - "liquid assets"?). It feels like the lesson taught one meaning but the flashcards are testing another. Maybe just sloppy AI work?
