Hello,
Thank you for contacting us and sorry for any inconvenience that this issue might have caused.
It appears you missed our last reply on the other ticket: https://support.rankmath.com/ticket/toc-issues/?view=all#post-825017
The TOC block you are using is not the one from our plugin.
The one you are currently using is from Ideabox which seems to be a custom block from a theme or plugin.
To add our own you need to add the block called “Table of Contents by Rank Math”. Our TOC only works with the default Gutenberg headings.
Hope that helps, and please do not hesitate to let us know if you need our assistance with anything else.
