There are few things that could go wrong if you don't see FAQs on page where you expect to see those.
1. You haven't enabled a feature. Make sure following feature is active.
Go to App > Design & Settings > General > Show faqs on other pages & create multiple faq pages > View Settings & make sure it says "Active".
If not, then please activate a feature.
2. You added a code for category or question which is set to be not visible.
Often time it happens that category is set to be not visible on a frontend. Please make sure question and category are set to be visible on frontend.
3. You added a code snippet in text field rather in HTML format while adding it to CMS page.
Make sure code is added in HTML editor and not a text editor. If you add it in text editor, your code would display as is on a frontend.
