Posts are above author post?

I am having problems with the forum and when someone posts, you see a post above the author

Example :

Poster 1 : -Insert post here-
Author : -Insert topic here-

General>Categories and forums
Click on any forum name
Sort the posts of a topic by :Post's date(most oldest in first)
Save
Hope that helps

Merry Christmas

Oh thank you
Merry Christmas to you too
