"Hover Effect" and "Link Image" does not work correctly

Unfortunately, I have some problems with the "JUX Gallery"

1. The "Hover Effect" (e.g., Slide To Right) is not displayed correctly. Only "SlideCenter" is displayed correctly
2. "Link Image:"> "Only Image", no "Description" is displayed

Here is my test page:

What can I do against it?
