Cant connect United Domains with Webflow - cant add cname and a records


I cant figure out how i connect the Custom Domain with United Domains. Here are the domains that i have to connect:

But i cant add @ to the “Domain / Host”. If I leave it “” and only add the adress, webflow says it is connected. I dont know if its supposed to be like that. I also cant add the cname. Its just greyed out.

Here you can see that its just greyed out. So I still cant add the cname. Its not editable.

How can I add it correctly and make it work? I hope someone can help me with it :slight_smile:

Thank you!!
