Recent Update changed menu text

I can usually change my menus to upper and lowercase using the TinyMCE editor. However, that doesn’t seem to work with Newsmatic. So, I entered the following to my CSS in the Appearance area:

.main-navigation a {
text-transform: lowercase;
}

.main-navigation ul ul li a {
text-transform: lowercase;
}

However, The Tag Line Is Still In Title Case

Today, when I updated the theme, the menus went back to ALL UPPER CASE. My snippet is still there. I’ve looked at the site in three different browsers. I’ve refreshed the page from the cache.

Any ideas?
