If it was indicating full when you emptied it give it some time for the residual water to dissipate. Then again, maybe there is an issue.

First step ignore the lights and learn when your tanks are full by experience .......

Sorry the indicator lights are poor at best and commonly mess up. Crud gets on the sensors... Some one l be along for help. I personally am from the days before the indicator lights came out and just ignore them..

Or d you have another dump handle maybe behind a wheel ??

Soap suds/scum can cause a false reading long after it is emptied. You'll learn just by experience to be a better judge than the indicator can ever be.

Circular argument. End result: experience will be your guide.
Gauges sometime work or not.
Mine unit is on sewer hook up for months at a time. Valves closed except to DUMP and back rinse.
Always black first; both gray, then sprayer system. Last time it showed "full" black; 5 people used it another week. Never got anywhere close to full.
Cheap; unreliable gauges.
