You have probably selected the "print index at the end of book?" option in the "Create a Report" menu. The non-bold name should be inclosed in some symbols like [xe "name"]followed by the name in bold. What you are seeing is the non-printing index entry marker for a word processor. If you are using MS Word you can hide this marker by clicking the paragraph symbol in the Word tool box. Word Perfect has a similar show/hide option. Then you will only see the name in bold text which is the standard for many type books.
The word processor does not automatically build the index from the .rtf, it must be instructed to do so.
