Spreadsheet node doesn't output empty cell parameters?

This seems like a bug, but I just want to make sure

In the first row of a CSV I’ve uploaded, there are a few values missing in the first row so those values are not showing up in the expression variable selector in the next node over

Shouldn’t all the columns show up whether or not the first one has a value? Presumably some data may be missing in some entries but that doesn’t mean it won’t be available in other rows

Did you try setting the Include Empty Cell option to true?
