Display coding field value on a request form

[Update: Resolved: It is showing up correctly now]

We want to display the value of a coding (classification) field on a custom request form. The field in question is "bbgm__Request__CODES_4". We have checked the "Display value from BBGM" checkbox, but the selected value is not appearing on the applicant's portal. (Show up as blank).

How can we display the selected coding value correctly on the form?
