Stuff to try:
It might not be ACs fault it can be another program that is taking over the keys. Either change Keyboard layouts (to US) to verify or check under System Prefs -> Keyboards ->Shortcuts and/or Text
Additionally you can try rebooting in Safe Mode and open AC to see if the shortcuts work, if they do then that could mean that another program is at fault.
