Force Show Menu button (Soft keys)

I've updated to the latest nightly build of Pacman ROM, and then updated it through recovery (wiped: cache and Dalvik Cache) and the system boot up and everything works great but there are 2 exrea menu buttons (softkeys, on the left side of the screen, and on the right side) and actually they are a little bit dimmed. Is there amy solution to remove this extra menu soft keys? Thanks in advance.
