In that case that is the version you have installed.  You could search
your PC to make sure there are not two copies of the executable file
in case there is another version lying about.  The command
which nut-monitor
 (or whatever the executable you are running is called) will tell you
where the one you are running is from, assuming you are running it
from the command line.
