EasySocial and sh404SEF

Hello,

I'm starting to use sh404SEF, and I notice that there is a strange thing with EasySocial.

My MainMenu contains links to the main sections of EasySocial.
EasySocial is on the homepage.

Once sh404SEF is enabled, all EasySocial links get this structure:
domain.com/groups/groups/groupname
domain.com/pages/pages/pagename
domain.com/events/events/eventname
domain.com/videos/videos/videoname

For other links, not added in the MainMenu, the structure is as follows:
domain.com/social/username
domain.com/social/polls
domain.com/social/friends
domain.com/social/albums
etc.

In summary, sh404SEF produces urls like this:
domain.com/menutitle/applicationname/itemname
Or
domain.com/social/applicationname/itemname

Whereas one should simply have:
http://domain.com/menutitle/itemname
Or
http://domain.com/applicationname/itemname

Elements to be deleted have been highlighted.
I hope I managed to make myself understood.

Thank you.
Philippe
