CNAME record not updating on Webflows end (SOLVED)

I have added a custom subdomain/domain into my hosting settings for my webflow site:

I have set my CNAME and A records correctly under my DNS zone:

MSlookups elsewhere are picking up proxy.webflow.com but it’s not showing up in the Webflow settings, instead it shows the previous CNAME entry?
