My sensors gets weak signals often so I have to reset them again. After having some performance issues I noticed that my sensors were getting weak signals. I tried to set it up and my sensor setup gets stuck at the touch recognition and sensor set up stage. It keeps telling me to go closer to by front sensors. It won't do it correctly. Now I'm all F'ed up in my space and height is messed up too. I think some people are going through the same thing.
