Q: trying to deauthorize all my computers but none are allowing me to do so

I have been trying to deauthorize all my computers but it says that I already have 5 authorized computers and will not allow me to deauthorize any of my computers around the house because they all say that they are not authorized, but it says I have 5 computers already authorized, so I am very confused as to what to do. I want to authorize my computer but I can't because it says there are already 5, but none of mine are authorized.
