Colorado Air and Space Port problem reports

When developing a flight plan with KCFO as either origin or destination I am told it is an unrecognized airport. If I use the old identifier of KFTG, it recognizes that as Colorado Air & Spaceport which is the correct name but the Identifier is KCFO and not KFTG. This only happens when trying to generate a flight plan. If I do a search of KCFO it correctly finds that identifier but not when using the identifier in a flight plan
