If you look at league lists through the account section, when a League is in Training Camp stage, no season is provided for it - this is inconsistent with every other stage.

If you're in the league it's no biggee, but if you're looking at Available / All leagues, you then can't tell what season the league is in within then going into the league.

Edit: I'd be happy to see the Training Camp text to be {season} Training Camp.
