Added Schema via Code Injection but not working

Developer help
1

Hi all,

I have added FAQ schema to the following page’s header via the code injection section - I tested the schema in Google’s Rich Results testing tool to check it worked (which it did) prior to adding it to the page. However after adding it to the page, it’s not working, it doesn’t pull through at all.

Any suggestions?

Thanks!
