Easy Fancybox doesn´t work right with slim jetpack

Hey guys,

i have a little problem with the easy fancybox plugin when i enable the tiled gallery created by the slim jetpack plugin.

my problem is: when i add a gallery into a topic or a page in my wordpress blog everything works fine and i also can open the pictures of my tiled gallery with the easy fancybox. but when the photo is opened with the easy fancybox i do not see the arrows within the box to jump to the next or the previous picture without closing easy fancybox.

any suggestions how to may fix that problem? i use easy fancybox Version 1.5.5 and slim jetpack version 2.3.3

here is a topic of my blog where it doesn´t work right:
