front page look

I am using the Leaf theme with a lot of fun,but there is just one thing that i can’t figure out.When i am looking at my front page i see the slider.Underneath the slider there are my categories.It starts with APPARAL.The first picture that you see is the PATTA article. And next to it 3 other articles.But after the Patta article i posted an other article in my apparal categorie,but the picture and article is not showing in the part of the blog. So that the patta articles moves to the smaller pictures and the latest post comes in place of the Last article. And that is with all the other categories also.I shows up in my slider,but not in the front page categorie part of the blog. Hope anyone can explain me if thats possible ..because now everytime i post a new article it doesn;t change the pictures..
kind regards mischa and hope to here from anyone soon
