firewall rule issue

Hi sophos community

i have an cyberoam CR25iNG and i upgraded its firmware to SFOS 16.01.2 and except below configurations , all other settings are factory default configurations .
i wanted to give internet to my LAN clients using identity so i used PortA as LAN port and PortB as WAN port then i created a firewall policy that gives Internet To LAN zone Using MASQ

NAT and i also marked the "Attach Identity" Button to use Identity based Rule and the applied the rule .

i have to mention that i only have one firewall rule in my appliance and there are no security policies like IPS , WAF , Web filter or etc in that rule .

now when i'm trying to use internet as a LAN client , the Web filter Notification will appear whilst i don't have any Web filter rules and i didn't use any default templates for web filter 

so i checked Log viewer which says that this problem is happening because of Firewall rule ID=1 (which is the only rule i have) and Web filter ID=2 which is deny All template which i'm not using in the policy .

i deleted the policy and created new one but it didn't work and i have to say that when i unmark the "Attach Identity" button , everything work just fine .

so is there any idea how can i fix this problem ?
