I add supplemental AutoDealer schema to my client's sites which matches the id of the JSON schema the auto dealership platform implements. I'm doing this across several different auto dealership platforms. The supplemental code used to validate just fine in the structured data tool and combine with the other script. But now I don't see my JSON script anywhere in the tool or code the tool grabs. However, GSC shows all of the values together under AutoDealer and I see my supplemental script in the Inspect tool and when I put the 3 different raw JSON scripts in the testing tool it all validates fine.

Anyone else seeing this?
