That looks like a TOC page.
Does it just replicate (same stuff, in plain text) the NCX entries?
If it is a separate file it may be easy... Replace it.
Not Separate, first split it off using the 'split here' feature in preview
Then delete that part.
Now regenerate:
Tools: Table of contents: Insert
Inline Table of Contents
Move your new TOC file (up<>down) to where you want it in the file list
If the inline TOC has visual style: S&R (your original question)
REGEX
Replace with nothing CURRENT FILE
