I could confirm the issue on mobile.
This can be due to plugin conflict on your site so please try temporary deactivating all plugins except Unyson plugin and WpBakery page builder plugins and see whether everything works fine and then enable the plugins one by one to see which plugin is conflicting if any.
Could you please try updating the WPBakery Page Builder plugin to the latest version on your site?
Also, would you mind if I log in to your site and do some troubleshooting? If this is ok then could you please temporary share me your site admin login details privately by adding them in the box having text “Enter your private content here (only you and forum moderators will be able see it)”?
After troubleshooting the issue on your site, I could confirm the issue on my test site which occurs when we do not select any Social Share Icons as displayed in the attached screenshot, therefore, notified the theme developer about this so that it will be fixed.
The issue will be fixed ASAP.
I have resolved the issue on your site by disabling the share icons in the theme settings as shown in the second attached screenshot.
