I am afraid to update my article.

I am an occasional blogger and write articles here occasionally. Recently I have published an article, it listed on c-sharpcorner successfully. But I found, the category I choose for my article is wrong. so I updates right the category. After doing this when I visited c-sharpcorner, suddenly my article is removed from the list. and same time, I found my article is under review process. Suggestion: I think the article should be remain listed on the site. If an article is updated by author don't show that updates to peoples. Updated article should be shown to peoples once it's approved by moderator. This may help improve article publishing flow.
