Hi Megan,
Sorry to hear of the problem you are having.
I have tested it on my test site and it’s working fine for me using latest version of jevelin theme. Also it is working fine for other users so it seems something is happening on your site causing these issues.
Not to worry we will troubleshoot and fix the issues.
First of all please make sure you are using latest version of theme and plugins.
This can be due to plugin conflict on your site so please try temporary deactivating all plugins except Unyson, Slider Revolution and see whether everything works fine and then enable the plugins one by one to see which plugin is conflicting if any.
Best regards,
Shufflehound team
