Priliveged Command not working?

I am testing Discovery on a Unix host.  I am getting the following warning message with my Discovery Scan. 

Sorry, user xxx-xxxx is not allowed to execute '/usr/sbin/lsof -iTCP -n -P -F pcnfT' as root on UnixHost.site.corpation.com. - Exit status: 1

note:  xxx-xxxx = this is the configured Unix credential

I researched the docs.servicenow.com and cannot determine specifically what I am missing.  I added to the Privileged Command 'lsof' and assigned to the Mid server. The Unix credential account does have enough permission to use the 'lsof' command on this specific endpoint.

Any suggestions to how I should resolve would be most grateful. 

Thank you
