Problem loading toolbar icons JCE - ES events front end

Hi

I wonder if anyone else have problem with loading EasySocial events toolbara icons for description with JCE editor std correctly front end bcs toolbar icons disappear there.

You set up JCE as prefered editor administrator/index.php?option=com_easysocial&view=settings&layout=form&page=events&tab=layout.

See attachment so when you when you try to insert one event with JCE the toolbar looks like this. JCE editor toolbar icons works for other part of the site. TinyMCE works fine there with no problem loading all toolbar icons if I change to Tiny.

Cheers!
