Yeah it still makes no sense to me. I have gotten 4 ingredients so far and never saw anything unusual about other resources on any page. Perhaps its not obvious at all, or the shadows or shading is a problem or something. Also, how do we combine ingredients with only 1 box? Definitely not intuitive at all, with or without notes.
Really love the UI in general, and most of the gameplay mechanics (school is still awful), but just wish things didn't need so much explanation to figure out how to even begin.
