So this is my URL https://www.rosterelf.com/pricing.
And if you go to page source, I have added 2 Schemas Product and FAQPage.
Then I went to https://search.google.com/test/rich-results and pasted my URL to test the schema and it gives me no error.
Then I went to Google and pasted this in search site:https://www.rosterelf.com/pricing but it only gives me review schema in result. My FAQ schema is not showing.
Can someone guide me why its not showing ? Is it because I have added multiple times <script type="application/ld+json"> for both the schemas ? Or any other reason ?
Please Guide me how can I solve this ?
Thanks for any feedback or suggestion.

The content of your website mentions the legal name RosterElf Pty Ltd in the footer. There is no information in the content about the name's connection to your website, and there is no easily verifiable confirmation of the name's legitimacy. In the content of your website, I did not find comprehensive information about the business behind the website, including information about legitimacy. Thus, the content of your website represents an unidentified business and an unidentified publisher. These are signals of low trustworthiness of the content.
In the guide FAQ (FAQPage, Question, Answer) structured data Google tells us:
Google probably considers your unreliable content as little-known.
