membership 2 option sliders don't work

I just frshly installed wp 4.5.3 and plugin membership 2 pro. While trying to configure it seems ALL option-sliders don't work. For example, on http://scrim.pro/wp-admin/post.php?post=122&action=edit I can't change the memberaccess to any of the created memberships.

Also due to this I can't enably any addon.

can you please help?
