There's a control panel that is for turning on the lights, HW tank, water pump, slide out, etc. That same control panel also tells us how full our water tank, gray tanks and black tank are. I've dumped our tanks (black first followed by the two gray tanks). I know that they are emptying because you can feel the water rushing out through the dump hose. I then rinse out the black tank by utilizing the built in spray system (keystone calls it "no fuss flush kit"). When I check the status of the tanks on the control panel it shows the gray and water tanks are empty, but the black tank is 3/4 to completely full. Anyone run into this before? If so, how did you correct it? Thanks in advance for your help.

I think by now, from reading everyone else's answers, that you have probably figured that the sensors are pretty much useless.
As a simple solution, I will share what has been our experience.
We just got home from being on the road and living in our rig for 4 continuous months "Snowbirding" it.
I never once looked at the level indicators on our tanks.
We, too, have 3 holding tanks, 1 gray for the kitchen sink, 1 gray for the bathroom shower and sink and the the black.
The kitchen gray is smallest, and we found that for the 2 of us, doing up dishes once a day on average, that that tank would fill first, in about 1 week. We knew because the sink would no longer drain
.
When that tank was full, I would drain all 3.
Simple as that.
I realize that's not as convenient if you happen to be boon-docking for an extended period, but for when you are hooked up, as we were for the most part, it worked for us and I didn't give it much more thought.
Happy camping, don't pet the sweaty things
