Im having trouble customizing the theme. Under

Hi, Im having trouble customizing the theme. Under the customize menu, under the site title and tagline, its not allowing me to make changes. Is there something that Im missing? I already have a title inserted but nothing is being changed. Can you please give me a clue on whats going on?

The site is at http://www.consolidatedenergyllc.com

Thank you,
Virgil
