Navigation block and Main menu problems

Hi all, I've been building up my site content but have been getting stuck with my navigation block contents not displaying my main menu correctly. What I see: Linked dot-points, left aligned not in any button format. See exactly as below! But what I would like to see is the buttons right justified as displayed here on the organic food default site. I would love some help, even if it just saying to enable a feature or module, but from what I've got so far, everything is enabled.
I appreciate this forum being available, I have solved this problem through enabling the DrupalExp Dropdown Menu 1 :)
