If table of content is enabled - will be exported into HTML, but position incorrect and anchors don't work (they are missing)
Can you transform this block or exclude from copy as HTML?
If you want to change this block, then here are a couple of suggestions:
place the block at the very top of the page
convert the block to a table of contents with working anchors and remove unnecessary elements
