On a question, when I click "turn into model" the query breaks

This is super frustrating. I have a question that displays data. When I click the button that says "turn into model", all of a sudden the query breaks with the error "ERROR: column source.Email does not exist
Hint: Perhaps you meant to reference the column "source.Email_2".
Position: 399"

When I turn it back into a question, it works fine.

metabase version?
