Gray/Black Tank Sensor Switch

I own a 2019 Tiffin Allegro Open Road 36la. On a recent trip, I noticed the black and gray tank sensors might be switched. I didn't notice it previously because I generally empty both tanks at the same time. Because we had a guest recently, I emptied the black tank without emptying the gray. But the panel indicated a full black tank and an empty gray tank. I then emptied the gray tank and the black tank indicated empty. I verified this again after several days of use.

We just arrived home so I plan on contacting Tiffin soon. Unfortunately, our warranty ended in November. Just in case I am on my own, and if it is not super complicated, I would like to try to fix it myself.

Has anyone ever seen this before? How hard is it to switch the sensors? Any help would be appreciated.

It would be MUCH easier to just switch the wires. The sensors are usually glued onto to the outside of the tank.
