Google Updates Fact Check Documentation to Specify They Might Not Show Multiple Fact Checks in SERPs
https://developers.google.comIf you have a web page that reviews a claim made by others, you can include ClaimReview
structured data on your web page. ClaimReview
structured data can enable a summarized version of your fact check to display in Google Search results when your page appears in search results for that claim.
They recently updated that documentation to specify that they are still working on way to display multiple fact checks for a single page, and that you may not see a rich result that features multiple fact checks in Google Search right away.
In my experience when they say something like this I would only include one ClaimReview items on a single page, comment out the other bits from appearing not he page and when they enable this feature in the SERP you can toggle that back on.
