Hi, @tommylzw, and welcome to our Netlify community site.
Those system records (of types NETLIFY and NETLIFYv6) are glue records which map the domain names to Netlify’s CDN. Once the traffic reaches our CDN nodes, the site shown isn’t controlled by these records but by the site settings themselves here:
As this domain is already configured at the URL above, no changes need to occur at Netlify. The differing name in the screenshot above is only cosmetic. We are showing the site
tommylzw.netlify.com for that domain name.
Can you confirm you are seeing the correct site also?
If there are other questions or concerns, please let us know.
