Along the same lines as what Mauam suggested, try using different keyboards. I don't have the problem myself and I'm using the AOSP keyboard built in to Novafusion's Carbon ROM. Maybe in your case it's a case of using Google keyboard or any of the other ones readily available simply because (forsome unfathomable reason) it hasn't loaded/installed all the functions.
Side note: you could also uninstall AOSP keyboard and reinstall. You can find a few FOSS keyboards on F-Droid, including a ported AOSP keyboard.
