[Mediawiki-l] question about "Unused files"

Hi, I have a question about "Unused files". We build a business wiki with MediaWiki 1.81. We have created ~250 articles and link a lot of pdfs. The syntax is: *[[:Datei:example.pdf|Example file]] When I choose on "Special pages" the item "Unused files", all these files are shown. When I look at the file usage,I read: "There are no pages that link to this file." I thougt, all these files should be listed, because they are linked on several pages. Am I wrong?
