Advanced Weaponry

Ive upgraded my entire base including every building (except walls) to their max level. Now the Advanced Research building gives me the option to upgrade it to Level 5 ONLY if my Command Center is upgraded to Level 11. However there is no option to upgrade it past Level 9. Please help, please start a forum, please do something. We are all confused. I want to get access to the advanced weaponry.
