Seasons are automatically managed by Golden Records from scores.  It uses the Type (eg Indoor) assigned to a round and the date the score was shot to determine the season the score should be in.  If a round is not assigned a known type a season will be created as Unmatched XXXX where XXXX is the year the score was shot.

Check that all rounds have a known type assigned and then rebuild the seasons table.  To rebuild the seasons table do the following:
