ESS 4 - port scan

Hi Guys ,
im using ESS4 and think about to buy it, i like the AV -> its SuperB , im testing the suite now , it works nice. One thing what i saw when i made a portscan , i have not a perfect stealth result. The firewall is also not bad.
Closed Port on 113 - Authentification service .
All Other Ports are Closed.. How can this affect my security?
teste made on Shields Up .. grc.com

One Other Question is about the matousec testing of ESS3 - which was not so good - did u get or given a feedback on it ? .. could u pls give me some info ..

Thanks JR
