This post is for all of those people who are having the same confusion/problem that I was having.
I had posted earlier in another part of the forum that I was having an issue where I put in this string:
Title=title;Sub Title=subtitle;Article Title=articleTitle;Article Sub Title=articleSubtitle;
into the edit_css_selectors and put the path to my stylesheet in the editor_css_path fields, and the result was that I had every style spec’d out in the stylesheet listed in the styles menu of TinyMCE.
It wasn’t until after reading this topic that I saw that there are two areas that you can enter css selectors. Make sure, to avoid the same confusion that I had, that you filter your settings away from the core settings and to the TinyMCE settings and you enter your css tags in the tiny.css_selectors field and not editor_css_selectors
