Unidentified configuration error

Hi,
I keep getting the “Multiple form controls are in a single label element.” error. I have tried everything, even removing the entire checkbox field and line and codes and everything and nothing works. I have also moved the file upload label tag back and forth and nothing. Can you please tell what I am doing wrong?
