Header symbol won't insert

Hi there

It is very early days with this site and it mostly has no content.

I am trying to get the content and structure right but I keep having issues getting the header into CMS collection pages.

You can see this page has the footer “symbol” but it won’t let me instert the header symbol?

The main site standard content pages allow it, but the CMS collection pages keep refusing it, saying: “There can only be one instance of this element in this component.”

There are no other instances of the header on the page, I have expanded all of items in the navigator, you can see them here:

What can I do? I need the header to be the same as the rest of the site…

Apprecaite help in advance.
