Dutch/Flemish vs English in Website Strings

http://musescore.org/en/admin/content/pages has two strings in Dutch/Flemish rather than English

Aangemaakte pagina's
Taal

While I'm sure that 'Tall' is "Language" and therfor can translate it to German ("Sprache"), I have no idea what "Aangemaakte" means, "pagina's" probably is "pages" ("Seiten").
