Impossible to display player score?

Hello,
I’m trying to play the Definitive Edition but my game currently refuses to display player score in-game. The forum says to go to the UI tab to change the setting, however my game does not even have a UI tab in the options menu. It has the rest- audio, graphics, interface, etc. but no UI. I have no idea what to do about that. Please help me fix this because it is very irritating

In the game, click the flag icon near the minimap or press F4 to display player score.
