Hello,
Thank you for contacting us and sorry for any inconvenience that this issue might have caused.
You can simply set <p>
tag instead of heading tags for your FAQ questions from the block settings and they won’t show up in the TOC:

We hope this helps. Please let us know if you have further questions or concerns.
Thank you.
