It's because the menu is written in 3 different places for the 3 different areas, and when I update one I don't always update it everywhere else. The way the site and Pokebase are done it's difficult to just import the design and menu from the main site automatically. Also the meta uses a different theme to do the grey so the menu is repeated again.
HOWEVER in the upgrade all the Q&A will use the same menu as each other so there will only be 2 things I need to update :D
