New ceramic cooker has marks on top?

So I’ve just bought this new Siemens cooker, and after the first use, I noticed these marks on it. What is it and how was it caused? Also how do I remove them. The outer ring is not elevated but there is a thin white ring in the middle that is. The other small circles are all elevated. It does not come off with wet towel, and is very tough and stuck to the stovetop really well.
