menu bar has unwanted arrow bullets

Hi, the main menu bar on my website kinkyinthecloset.com using tempera theme 0.9.8 has downward pointing arrow bullets that I did not purposefully insert. They are blocking letters and words on the menu bar from view and I would like to remove them. I would like to keep my submenu however and I have a feeling that those arrows are there because of that any help in removing these arrows would be much appreciated thank you
