Submenu names appears in top right hand corner of Website header area

Hi Folks, since installing the Jackson theme and setting a series of submenus I am experiencing the following problem.

Note: You can see / experience the problem on my pre-release website at www.akonia.com/drupal

When I click on "Consultancy" or "Services" menu titles, I see the corresponding submenu titles appearing in the right hand corner of the website header section, as well as underneath the menu titles.

I don't think that the submenu titles should be appearing in the header section and would like to know how to prevent this.

I'm novice with Drupal so simple explanations and fox procedures please.

Thanks for your help in advance ... Gary
