Tag Links Bug?

I have 2 tags "Pima" and "Styles". My Moz SEO report showed duplicate titles for the 2 tag links... blog/tags/pima.html & blog/tags/styles.html. When you click on either of the links, it takes you to the tag page but displays no entries related to the tags... only tag links. I removed and re-added the tags to the system, but still no luck. I tried various logical methods to try to get it to work, but they always show without entries and the page title for both pages is the name of the blog, thus, duplicate page titles. There are 20 other tags that work perfectly.

What could possibly cause these two tags to act differently than the others?
