[Can't join network game?]

My friend and I are also having the same issue so seems to be a FM wide problem

[Substitutions]

Evening,

Apologies, not sure whether this would be the correct part of the bugs forum.

Playing an online game in Serie A, and the game has allowed us to make 6 subs in a league game? Rules state 5 in the game, not sure whether anything has been changed but google suggests it is still 5 IRL. 

Attached the match where I first realised I could do this, in the other leagues I have tried it hasn't let me. Also image attached which shows the 6 players I brought on.

Thanks
