Duplicate Table of Contents Issue in Brizy

I’ve run into a strange issue while working on a migrated WordPress site using Brizy. The Table of Contents (TOC) block is duplicating itself on the frontend, even though only one TOC element is added in the editor.

What’s odd is that this doesn’t happen on my clean testing site, everything works as expected, with no duplication at all. Only Brizy and Brizy Pro are active, so plugin conflict seems unlikely.

For now, I haven’t found a definite solution.
