The "Heavy X" and "Light X" themes allow you to have portrait-less player and opponent frames.
In order to make the right-click-menu work on the player's frame, a mini-portrait had to be placed (and so covers the level indicator).

• You have to uncheck "3D Object Portrait" in the options panel. (Options > Adv. Graphics > Performance > 3D Object Portrait)

Now you can see your level indicator and can have the player menu by right-clicking on your level.
