How i can remove a domain from Smart URL?

Hi everyone,

I have some troubles when using Smart URL in Marketing Hub. Can you help me?

The first,

I chose a wrong domain and now i can't remove it to replace a new one.

How can I remove this domain from Smart URL?

The second is:

What do I need to do to display the indicators at Touchpoint?

Now this part of me is empty, although I have done everything.

Thank you for your help.
