Structured Data (Site Name) Issue on Ghost Generated Schema

Help me solve Structured Data (Site Name) Issue on our ghost site.

SEMrush detects this as an issue: 2 structured data items are invalid.
Field: Name
Issue Description: A value for the name field is required.

Upon checking on Schema Validator it has NO ERROR or WARNINGS but the site name is missing.

We tried overriding the schema by injecting code, but it still didn’t work. We used AI to help us with this and tried every possible solution, but nothing seemed to work.

We think we need to disable the Ghost generated Schema? Any suggestion?

So…? Does updating fix things?

It should be possible to inject an additional schema in code injection. What did you inject, and what happened?

It is possible to disable the ghost generated schema if you can edit your theme, but you’ll have to upgrade to a version that supports it.

Still SEMrush respects Ghost-generated Shema, even we do code injection like this on the website’s code injection tab:

We also tried code injection via Ghost Theme edits but still didn’t work. When we check it with view-source we got 2 Schema on site, one from Ghost-generated and one from what we injected on theme. You can check it here in our URL.

What version do we need to disable the ghost generated schema?
