Nope – its not.

And no other code targeted at this particular field other than registering the form itself and setting candidate email as an admin column on my post type in Wp-Admin.

Here the form code for reference:

// 1. Candidate Application Form

    //Defines the fields to display
    $fields = array(
        'field_5db9db36a28bf',	    // candidate first name
        'field_5e06338abb373',      // candidate last name
        'field_5db9db5da28c0',	    // candidate email
        'field_5db9dc8ca28c1',	    // candidate contact number
        'field_5dcc08f0a11b5',      // candidate gender
        'field_5dcc092ba11b6',      // candidate race
        'field_5dcc09e2a11b7',      // candidate nationality check
        'field_5dcc0a32a11b8',      // candidate nationality
        'field_5e42e3cf90206',      // candidate work permit check
        'field_5e42e43490207',      // candidate work permit doc
        'field_5e42e30990204',      // candidate notice period
        'field_5e42e35190205',      // candidate disability check
        'field_5e42e47390208',      // candidate criminal record check
        'field_5e5bf8b8e879b',      // candidate language proficiency
        'field_5db9dd10a28c2',	    // candidate cv
        'field_5db9ddf5a28c4',      // candidate supporting docs
        'field_5dba152669aaf',      // candidate vacancy applied for
        'field_5dcc0f15030b6',       // candidate disclaimer
        'field_5ec4e941df19d'       // duplicate check
