Display all categories

I recently bought this extension and I have a problem,
I have 4 categories to display but in front-end it shows 3 categories.
How can i view all categories?

I bought the JUX Mashup extension, installed the module but more than three categories did not appear on my frontpage. If I select more than five categories, nothing appears on the frontpage. Can you give me a solution? I have an online newspaper sibam over ten categories of articles.
with thanks
