Bus Frequency Output

I am trying to test the frequency response of a system. After I run a simulation and view the frequency of the system from the output file I am essentially getting 0 for the frequency of the system.

I set the base value of the system at 60Hz so shouldn't my frequency be 60Hz in the output file without any faults placed on the system? I am trying to run a Over/Under frequency trip test but I can't even get a frequency reading of greater then 0.

Does anyone know how I can generate an actual frequency reading? I can't find any setting in the save file or dynamic file that will fix this issue so maybe it is my PSSE seetings?
