Tiled or Carousel freeze the post

When trying to view a gallery made by Jetpack gallery it seems to freeze the scrolling ability of the post. That happens after viewing some photos and closing the gallery, the post is frozen and I have to refresh the browser.

NOTE: I also had to add the clean_gallery plugin to make it work.

Another problem is the arrows to move in the gallery, they are invisible…strange.

I did not have this problem before so I am not sure why it is a problem now.
