Can't change title of my store

I need to change my store’s spelling from “classic-cushman-apparel” to Classic Cushman Apparel. No matter what I do, it reverts back to this improper spelling on the start page that customers see.

Hi, you can just change the teaser’s headline under “Pages > Start Page > Teaser”. I already changed it for you. Greetz

Thanks for the help. I finally found the URL to do such settings.
