If I create a second “Organic formulation” column, it shows us as a duplicate column (with the x), even though the first one isn’t listed. If I delete of of the two columns, it doesn’t show up again.
Actually no, I thought I saw it, but I can’t reproduce this. Could you tell me exactly how to reproduce this in your app, please? Maybe send a video?
Note: If the “Options sheet” is the same as the sheet that’s edited in the screen, then you won’t be able to pick the same column. That is by design, because it allows weird things to happen.
