MLS League Name Missing on Player's History

Started a new save a few days ago,

And as you can see, MLS seems to be entirely missing on the history tab.

Active players, retired players, just all of them 

unless it's the “CURRENT” season (not sure if it stays after it moves to next season)

Is it a bug or did I do something wrong?

Yea I am very curious on this too…wonder if its to do with one of the Inc files 🤔
