What is happening here is that the server is producing NaN (Not a Number)
as a value, probably because of some impossible calculation, such as
3.5 / 0, which can happen inadvertently for some indicators.  The GUI
doesn't now how to display a NaN as a value, so it converts it to 0; but it
tells you about it so that you will know that the displayed value is not
really correct.  [The actual value would have to be displayed in a parallel
universe :-)]

In other words, don't worry about it.
