That depends on how you have setup the JSON-LD Schema. Did you manually type the details inside the schema or did you use patterns? If patterns were used, the data will be automatically changed based on the setup you have.
If you can send us a screenshot when editing the schema we can see what exactly you have on it.
Would you mind providing an example of a page, including what it currently says and what it should actually say? This way we can better understand what is going on your end.
As for if I believe it’s correct, that’s up to you, what exactly you wish to have for each schema. If it doesn’t change, and it should, then something is wrong and we are going to look into it. However, I’m not sure if this is the cause right now, not with the amount of details we currently have.
I’m not quite sure that I understand what is wrong.
Allow me to explain what the current patterns you are using are doing: Headline: {{sitename}} -> Adds the site’s name. (as it’s set up in Settings > General > Site Title) {{page}} -> Displays the number of the current page (i.e. 1 of 6) {{sep}} -> Places a separator between the elements of the post description. {{sitedesc}} -> Adds the site’s description. (as it’s set up in Settings > General > Tagline)
Description: {{excerpt}} -> Will display an excerpt from the post/page – as it appears in the excerpt field in WordPress for that particular page/post. If NOT customized, the excerpt will be auto-generated, displaying the first lines of text from your post/page. {{page}} -> Displays the number of the current page (i.e. 1 of 6) {{sep}} -> Places a separator between the elements of the post description. {{sitename}} -> Adds the site’s name. (as it’s set up in Settings > General > Site Title)
Essentially, none of the patterns you are using is retrieving data from the text blocks you sent in the screenshot. Not because of an issue, but because those are getting a different kind of information.
If you want that data to be pulled, first, you need to determine exactly what those are (titles, descriptions, product names, etc.), and use the appropriate patterns.
