Detailed Seller Information and Business Name

Hello.

I think this has been asked before but reading several old threads didn’t give me a conclusive answer.

So I just noticed that my actual name shows under the detailed seller information and when I try to change it, it states that because I am a single member LLC, I have to use my real name under the business name section.

However, my question is how am I seeing a lot of LLCs, some of which I know are single member like me, have their actual business name listed and not the owner’s name?
