Google ultimately decides whether or not they show the structured data; you can’t force them to show it on search results.

Common reasons for them not showing…

a) You’re trying to use multiple on the same page.
b) There’s not enough data for Google to believe they’ll be useful.
c) You didn’t configure them properly.

Google has a free tool to test structured data on your site. Try it out. https://search.google.com/structured-data/testing-tool
