Rich Text Editor

I had a quick question about the rich text editor. Personally I don’t use it because I know basic html. I do have another person who blogs with me who does use it but he just started running into an issue where he opens the page to begin posting and in the text box the home page template appears in there.

It is really bizarre. The blog is located in the /blog directory and the template being displayed in the text box is from the home page, or at least not on the same directory.

How would I go about solving this issue? Thanks
