If you don't see the icons at all, you need to update your game! Float your cursor over the far left one and it will tell you your base game patch version - you need to have at least patch version 1.12.70 or later.
Look down at the very bottom left corner - you should see some tiny little icons. The easiest way to find your game version is to open the game Launcher. Depending on what patch/update level you have (and any expansion packs), you may need some extra steps to get your.
