Nice plugin but not working fine!

The plugin is very nice to see but has problems in the viewing gallery and contact information button. Tested on all desktop and mobile browser, when it seems to have solved the problem it recurs constantly. Also it happened that I posted the shortcode in a page of the site and it’s changed by self-writing the code with “this browser does not support javascript” inside the text area! it’s crazy.
The assistance support is a bit slow. Too bad because it’s a nice plugin.
