Open the NavMap with a 'programmers editor' the colorizes key elements.

Everything will be INSIDE a pair of tags. The outer most is at the start, and CLOSES near the end. Someplace in the file, this got broken. you need to locate it.
  You posted in EPUB Merge. ARE ALL merged parts EPUB3? You might need to make them all the same (eg EPUB2) before merging |
I tried using Epub3 formatting for the three books just now but that does not help. I think there is a bug in EpubMerge, so I want to uninstall it from Calibre and reinstall to see if that fixes it. I cannot see how to uninstall it. Can you help with this?
