Number field, with default of zero, no data entered returns an empty string submitted via Slack by josh

BTW I'm testing with get_post_meta( $id, 'number_field', true ); which works as expected if the field has a value, but returns an empty string if not. In #support @shameguy4 reports same issue with Pods::display()

In the case of an ACT with a number field, default 0 but no data (the field is added after records are created) results in NULL from display() or field()
