Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for the delay.
Adding the FAQ schema through the Classic editor will be slightly different from using Block editor (Gutenberg). You can check this link for more information:

Unfortunately, using the field that you have created using ACF is only available with our PRO version. Here’s a sample screencast for your reference:

I hope that helps. Thank you, and please don’t hesitate to contact us anytime if you need further assistance.
