Name on Seller Central

I’m a sole trader, when setting up my account I remember seeing the option to create a shop name, which can be changed at any time. I can see how to and have done that, from the original set up. However I can’t change the original shop name that appears in a box at the top of my seller central account. On a desktop it appears at the top of the page that says Name | United Kingdom. Can anyone tell me where this name is pulling from, what it is denoting and if I can change it? As a sole trader I was only verified under my own name. Thank you
