Appearance of Comment # Notification on Home Page has changed

Hello! First of all, thanks for your great work on this theme. I've been using it for the last couple of months, and have been generally quite satisfied. However, a couple of weeks ago, something changed with regards to how the number of comments for a post is displayed on the home page.

I've attached a screenshot with an example, but a quick verbal description would be that it used to only show a number in a dialogue box, with no text. Now it shows the same number, but also the word "Comment" underneath, which takes up a tremendous amount of real estate, and it looks broken. When you hover over the post, the color of the dialogue box turns to blue and the word "Comment" disappears. I assume that's not clear enough, so hopefully the screenshot will help.

Here's the website address, so you can see for yourself:
