I have a few themes in the store and didn’t realize that my full name is setup as the seller. Is there a way where I can change it?

Contact the seller store for more information.

Under the Advanced section of the App Information tab, put your brand name in Copyright Holder. You can actually use different brand names but they will always point back to your named account.
However, on your Seller page in the app, your real name will always show, there’s no way around that.
