Another mysterious question (from @funker)
How this team can have those titles in history ?
His stats (games - wins ...) fit for his level but not for those titles,
A guess was that he took over a new club and those titles are from previous club too.
But no, I have a team (TIGRAN in some previous posts) that took over a new club, I can see the old trophies in manager's profile and the Treble achievement but doesn't count all the titles together in history. Now it has the cups of the new club only.
Top of the server (and repeating same level winning trophies) could be an answer if he had some higher LV. At lv17 ???
My guess, it's a bug from previous season bugs as some also were complaining that lost some titles from their history.
