When my page is tagged the post does not appear on the page`s timeline

When someone tags my page on his post, for some reason the post will not appear on the page`s timeline, nor would I get any notification to authorize the appearance of this post on the timeline, despite my having allowed in the settings of this page for visitors to post on the page. Even when I myself tag my page in my post, the post will not appear on the page`s timeline. How do I fix that? how do I allow posts by users in which my page was tagged to appear on the page`s timeline? (The page belongs to the 'people' category - it`s an artist page)
Thank you!
