A green checkmark indicates that you have submitted your lineup and there are no bench players in your selection.
A yellow alert can indicate two things: No lineup has been submitted for a match kicking off in less than 24 hours or one of your selected players is not in the starting lineup.
A grey status means you have not submitted any lineup in the team selection.
Once the match kicks off, the game will display the current points you have in that match. If you did not submit your team, then no points will be displayed.
