Field showing up after being removed.

This form:
https://form.jotform.com/60694707189973

I removed the field 'Study Position' form both the form and advanced fields.

It is still coming through in my submission as a filed.

Though the field was removed from your form, it was not removed from the autoresponder email:

Edit your autoresponder email and remove that line.  Click on save to finish.

If any other emails still contain the field, do the same for those.
