You might try checking underneath your rv. If you know where your black tank is, you may find two sets of sensors are on the tank. One set is wired, the other is not. The wiring is fastened with screws which easily are removed. Just swap sensors moving the wires to the corresponding sensor (top to bottom). I think they built the tanks with the back up set for this purpose. At least that is the case with my Quantum. Otherwise you probably have TP stuck to the lower sensor giving the false reading. A good high pressure wash down your toilet might fix it.
