I might be misunderstanding but there there are multiple games that won't show up on the various Playstation sites (US, UK etc.) trophy lists. Some will even show up on one and not the other. Not sure why Sony don't add them but it is normal and nothing that can be done to change it other than Sony adding the lists. The site will still register the right total trophy count though so they are not toally missing. Just missing lists for no apparent reason.
Better to use sites like
http://yourgamercards.net/forums/ minus how often that site seems to go down.
