Hi Rachel,
That was exactly what I needed to find the problem. I looked into your account and at that particular listing. I found that in the section where you choose a template, a "seller details" profile, and you can edit a title for displaying inside your template otherwise known as "Template Title"- you have placed the words "yellow and blue template" inside this field.
The "Template Title" is meant to give you the ability to change the title of your auction (at least INSIDE your template to something that you want that is maybe slightly different than your overall auction title. We found many people use a bunch of keywords inside their auction title so that people will find their listing but they do not neccessarily want that same title to be displayed inside the template. This "Template Title" will default to your auction title unless you change it to something else.
The only way to fix this auction listing now is for you to revise it at eBay. I suggest you edit the listing. In the description area search for the Phrase "yellow and blue template" and replace it with something more appropriate.
