UPDATE
The problem seems to be that I have some duplicate entries, but not on my spreadsheet/CSV.
Yesterday, while initially importing, I stopped an initial index table generation when I realized that I had not added the ID number that gives them a unique identity.
I stopped the index, and then deleted all the Books posts from my site.
I then corrected the spreadsheet/CSV and imported it again, then generated a new index table.
Somehow, the old entries remained and now they show up in the results.
I will start over later and delete all the Books posts and import them again. then delete the current Index Table and generate a new one. Hopefully that will solve the problem.
