For what reason the pictures of my facebook followers appear duplicated?

I do not know for what reason every time I log in into Facebook photos of my followers appear duplicated. This happens to anyone who visits my facebook logged on site, pictures of followers are all there in duplicate Like box on the site. Why is this occurring? Misconfiguration extra widgets jetpack? Are you modifying? Was to appear only one photo at a follower, be independent or not logged into Facebook, was not it? Anyone can verify simply enter the site without being logged into Facebook and then log into Facebook to see the difference there in the box Like the site generated by jetpack plugin (extra widgets).
