This is probably because Carpet allocates storage for these variables but does not currently use them for anything.  You are probably also running with the NaNChecker set to detect NaNs in all variables.  I recommend setting the NaNChecker to only check for NaNs in the variables you are interested in, as there are many variables like the above in a typical Cactus simulation.
