Web Filter (only for Endian's categories) not working with trasparent proxy

[Guest]

Hello !
My configuration:
ewf 3.0.devel
Proxy transparent active
Web filter profile ALL where I activated all Endian categories and antivirus scan checkbox flagged.
Access policy Source Any (tried also with GREEN but the same issue) and Dest. Any Filter using 'all'

I followed also help.endian.com/entries/20059468-Web-Proxy-Basic-Setup-Transparent-

If I try to browse some sites for example:  content websites, the filter doesn't work and I have access to those websites.

Where I find the websites list of the categories ? How I can check the Endian's categories ?

Where I can find a specific log for the web filter ? So I could check what happened when I browsed those websites.

Notes: my custom filters work !! Only Endian's categories web filters don't work.

Help me please ! Many thanks.
