Game version: 1.02
Found this in the roles of my AFLW team, St Kilda. The 2nd Ruck role says 'Captain' and 'Set Captain', but the slot is for the 2nd Ruckman.
Also, as no one is set, it says 'Text Block'.
Selecting someone for this position fixes up both the name and titles.
Also, I noticed in my custom team, that the 'Kick out' slot was also saying Captain....and the player selected was a custom player that wasn't even in the team.
Again, setting this to a player fixed up the issue....so it looks purely visual.
