Activity Monitor in macOS Catalina 10.15.7

When I try to glean any information from the Activity Monitor application in the latest version of Catalina, it only displays a column of process names without any of the other columns selected via the View menu. I have restarted the computer several times and this situation remains the same. In this condition the Activity Monitor is of no use. I am running this on a mid 2012 MBP 13" non Retina machine. Any help would be appreciated.

Thanks,

Bruce
