@rock, “Squadra” or “Team”, It does not make difference.
The picture in Italian and in English that have been posted do not allow doubts. Whatever the language is used any word in front of the slots numbers does not fit into those heroes headers that belong to ≥N teams.
Using a compressed font or an icon or nothing at all but the nunebrs only, it resolves.
By the way, what’s the problem in understanding the issue? I might have not express it in a proper manner BUT once some images has been posted, it became pretty obvious.
After all, there is a good chance that any player (except beginners) have seen this issue in their own app (as long as they used the same hero in many team).
