Black Sensor Question

We have a 2019 Keystone Outback 328Rl. Have noticed recently that when I drain the sensors still show 1/3 2/3 etc. I read alot of replies to other posting. I use the black flush and a Camco RV Flexible Swivel Stik. I alternate them and use at the same time. After I complete the black flush and Swivel stik my tank sensor shows empty. We left the camper (no one stayed in the camper) plugged in for 24 hours then when we came back we noticed the sensors were again showing 2/3 before anyone used it. Dont understand why they read empty but the next day were showing 2/3 when no one used it. Any help or recommendation is greatly appreciated.

Moisture, and probably some toilet paper hanging on the sensors. Put a bucket under the drain outlet and open the black tank valve. Leave it open for a while and see if it shows empty.

You're better off learning the sounds & length of time to fill the tanks & don't sweat the sensors not working or you'll drive yourself nuts trying to fix something that's not worth fixing.
