An additional Link to "Multilingual Wikisource" appears in the left menu below "In other projects" on the main page of most wikis. I think this is a configuration error or is it part of a wikisource promotion tour?

What happens?
Look at the menu to the left of the page. A list of links is displayed:
In other projects
MediaWiki
Meta-Wiki
Multilingual Wikisource
Wikispecies
Wikibooks
...
What should have happened instead?
In my opinion the link to "Multilingual Wikisource" should not be there.
