Drop Down Menu Gap

I'm not a web designer or code person. I'm just a graphic artist that happens to know only a little about Dreamweaver in order to make changes and updates to a current web site (or so I thought).

I have done it before, but it's not working this time...
I was asked to remove one of our locations from our drop down menu (God forbid we open a new location cuz I'll be fired, ha ha)

Anyway, I delete the little anchor thing, I do a right click and choose remove tag, I do a right click and select cut (not in that order, not always doing all of those, but I have tried several combinations of these) and I still have a gap between my locations on my drop down menu. Sometimes the gap has gray (after I do one or all of these things), sometimes I can see through to the page behind it, but either way I always have the gap.

Like I said, I did this before, but I have no Idea how I did it. Daaahhhh!!!!

Please, Please, please help me. =(

Thank you so much!!!
