DDJ Rev 1 Fx buttons on deck 1 and 3 malfunction

My rev1 dj controller is having an issue with the fx buttons on deck 1 and 3. When I hit #2 it doesn't light until second tap. Then the lock on and on functions don't work. When I hit the lock on or on it lights #1 and #2 but doesn't work properly. It also changes the view on Serato taking away the fx view.
