could be a bug?

i installed only the firewall last version Free Firewall | Best Comodo Firewall Software Download 2022

i did a test GRC | ShieldsUP! — Internet Vulnerability Profiling  
and i score 100%

after i clicked on the icon and i disabled the firewall
after few seconds i re-enabled the firewall ,clicking on the icon

did again the test , i did not pass

is a bug ?
i remember the same issue in v3

is the right place to post ?
now i’m running v5

I did just like you and passed both times!
