It seems one is from "Business information", and the other from "Public business info". I'm guessing the best approach is to change the business name in "Business information" to my ebay store name, though I don't have a registered business so have concerns about whether doing that might have any negative outcomes? Notably when changing this field ebay states "Please make sure your details are accurate. If we're unable to verify the updates you make, your payouts may be held."
