Is there something wrong with zoom adjustment? I have it to auto-zoom to contain all of the locations initially and my zoom adjustment at “0,” which should be perfect. However, when I set it at “0,” it actually is at the same zoom as when I have it set at “1.” And, if I set it at “-1,” it zooms in two levels, passing the one that I want. I went as far as using a default WordPress theme and disabling all of my plugins, and the results are the same.
