EHM The Blue Line

I had an injurie ( Schultz with EDM)

I removed him from the roster, but when I click on Tactics to make my lines ... nothing, can't access it. No bug report, no nothing.

Can someone help? I can't save since I'm about to start a game.

you might have left a screen open that needs to be properly exited from(usually an "ok" button). Scouting, practice, tactics and player/staff searches come to mind.
