They should be correct very shortly.
Standings should be updated.
Final Season Standings page for H2H seems a little wonky because of the playoffs. Basically any teams not playing in the playoffs lose the ability to view their stats on the standings page. Happened each week of the playoffs- not really a big deal then (and I suspect I get why it was displaying that way: only active teams are getting stats), but now that the season is final it would be good to be able to see all the final stats. For end of season analysis and badges and bragging.
Good call - this should be fixed now.
