Edge 840 not recording speed and distance

My edge 840 has stopped recording speed and distance. I recently connected a speed sensor and it works fine when connected. However, when the sensor is disconnected or even when using a different bike, with no sensor at all, the device is not recording either metric. Amy suggestions please? Thanks
