PCI Scanning Bug

I’ve just finished the test of our office and I got the result “Not Compliant”. I am opening the report that shows not compliant. I don’t have any service showing out from our LAN hence nothing to exploit the detailed report shows :
Security Holes Security Warnings Security Notes
0 0 0
Only one link is there :Go to report list
Clicking on false positive:
False Positives
Nothing found to display.

I HAVE CVSS SCORE 0.0 !
How come “NOT COMPLIANT” ?
I am definitely happy with this service.
