You have right, this is fixed.

So there are two current leagues as TFF 1. Lig, “league_id: 467” and “league_id: 779”. I couldn’t understand why the league having the attiributes “season:2018” and “season_end :2019-05-18” is still considered current. Shouldn’t it’s been renewed by the league “season:2019”?

I have call the endpoint and i have 5 results from several Turkish leagues and cups, For information a league is considered “current” as long as it has not been renewed by the new season.
