You don’t add up J and C to get number of Polaris seats available. At this point, UA is only selling 4 seats. J4.
As for fare classes, they are sold provided fare class provisions are met (advance purchase, round-trip, minimum stay, etc). B came back for your (probably) one-way short-notice trip. L’s restrictions probably make it unavailable with your travel date(s), routing.
