Category Problem..

I have set up 5 categories in the dashboard with the 5th having 3 child cats.
Only 3 of them show up in the display bar below the header image.

I do not have any pages excluded in the cat/menubar option.

I have worked all afternoon trying to solve this problem to no joy even upgrading the theme to the latest version.

Does anyone have any ideas on how to solve this problem?

Thanks for reading and any considered replies.
