Hello @sajad93,
The issue is due to the incompatibility of the plugin with the theme . Also for your information we have not done any compatibility testing with any third party plugin beside the one recommended by the theme itself .
However for the quick fix you can use below given CSS .
For this go to Admin Panel > Appearance > Customize > Additional CSS and paste below given CSS .
div#content section {
opacity: 1!important;
}
Hope this helps .
Best Regards!!
