It's possible there's no O&D D1 fare filings on route or there's simply no married segment inventory availability on flights. Hard to know exactly without knowing route and date to lookup inventory availability on ExpertFlyer.
Over the past few months I have had trouble upgrading automatically on a domestic non-BE flight to C+ as a DM with a PNR of just me with 50%+ of the C+ section open. This never happened before unless the PNR had 3+ people or C+ was sold out.
