Google Adwords Help

I work for a company and, by default, I have been dragged to help with your Google Adwords account, I only have a very basic knowledge of Adwords.

Each of our ads seems to have a text attached to the bottom of the ad, which makes the ad very badly read. I can not edit the information in the usual way, as it appears in gray, when I try to edit the ad.

Does anyone know where this information can be edited?
