History Tab - Remove Text "TitleContentExcerpt"

I have the Wiki plugin installed and it appears to be working properly. I'm in the process of customizing the appearance in the template files, mostly CSS.

Under the "History" tab there is a bit of standalone text in the "incsub_wiki incsub_wiki_single" div that I'd like to remove:

"TitleContentExerpt"

I can't find where, in the template files, this text is being generated.
