Index SEE [Title] hyperlinks not going to their titled topics

In my book Index, the Level 2 links are active and going to their root topics instead of the actual linked (marker) topic.  In other words, I have a main topic at Level 1 and at Level 2, I have "See [TopicName].  The [TopicName] link goes to the Level 1 topic, instead of the actual topic it should go to.  See attachment.  I wasn't even aware that the Level 2 topics were linked until I converted the document to an HTML file.
