It shouldn't have been rejected because of GameFAQs as they do not have a German release on their page.
Of the two German entries on the site, they are
"small USK rating"
https://vgcollect.com/item/136934 (which is the one you linked)
and
"large USK rating"
https://vgcollect.com/item/220100The small has a release year of 2007 while the large is 2006. However, I am removing the release year on the Large one simply because the rating shown on the cover started in 2009.
The Gamepressure link is not for a German version.
136934 has a date of 2007 on the entry and matches the Mobygames info, so that doesn't need to be changed.
