The thermostat probe should go on the outside of the tank in between the bottom of the tank and the uth. Don't tape over the sensor, only over the sensor wire.
The probe for the thermometer is on the inside of the tank, directly above the UTH lying on the glass. I'm not sure if all of the probes are as thick, but the one on mine has the thickness of a large nail, if that plays any part in not placing it between the UTH and glass.
