If I add a relation column in the data editor, how can I delete it? I have decided to do things differently and this old, unused column is bothering my tidiness obsession…
In the data editor you should have a little dropdown triangle when you hover over the relationship column header. From there you can edit the formula or delete the column.
It’s an array column, not a relation. Seems like you have Interest 1, Interest 2 etc on your sheet.
