Wrong number of "articles found" in results

I was just installing this plugin and it looks perfectly good for me, Im going to see if the Plus version satisfy me too but first I found an important and strange problem which shows a wrong number of articles.

For example, I just added 3 faq entries (3 in total), and it shows me 113 results for the word “a”, or 10 results for the word “usb”, as you can see in https://www.enlightenment.org/ss/e-53f27dd72a03e1.51774857.jpg

Thank you,
Samuel
