Greyed Fields in Cockpit

I am very new to cockpit and I noticed some fields being greyed out in an existing cms UI.
There is unfortunately no documentation on the website I am working on so I am struggling to figure that out.
There is a map section in the CMS where the location field has different values but they are greyed out. Some of these fields are not correct so I need to edit them so I am wondering are there other ways to add data to the cms aside from the fields and the Import function?

Sorry if my question is very broad. I am working on an existing cockpit cms project and after reading the docs I am still very confused.

Any help would be appreciated.

Maybe with screenshot will help
