View not displaying correct value

Application: essistmgmt/assets
Form: PRODUCT 
View: PRODUCT_View
Field: PORTFOLIO

I have a PRODUCT form with a PORTFOLIO_ID field. The PORTFOLIO_ID field is a lookup of the REF CODE form with criteria 'REF_TYPE == "PORTFOLIO"'. The Advanced Display Option is set to REF DISPLAY NAME

When I view the REF_CODE View & filter on REF_TYPE == "PORTFOLIO", the only values I see are

C CLOUD SERVICES
D DATA SERVICES
F FIELD SERVICES
M MANAGED INFRASTRUCTURE SUPPORT SERVICES
V VOICE SERVICES

When I view the PRODUCT View & Filter on PORTFOLIO contains "F", I see rows with "FLAT" filled in. When I Click "Edit" & check the PORTFOLIO field, I see "FIELD SERVICES"

Do you know why the display value isn't showing up correctly?
