2009 Trail Bay by R-vision V-series

Recently purchased. Having problems with tank sensors. Tanks read 2/3rds full when they are empty. It has 2 gray and 1 black and 1 fresh. The fresh water works fine. I have used cleaners and flushed several times with a clear fitting in place. I can't seem to get a wiring diagram for the panel. Just seems odd for 3 of tanks to read the same. Not my first RV. Any suggestions? Thanks
