Hello, @Wssrob
Please check this video of our test site with the same demo there is no issue it is working just fine: https://streamable.com/b45ris
On your site I disable all the third-party plugins then I delete the “XSTORE CORE” plugin after that I install it again by doing this your issue is resolved. Check the resulting video here: https://streamable.com/x915gl and then check back to your site after clearing the browser cache.
You can again activate all the third-party plugins on your site one by one and check which one is creating the issue on your site.
Regards 8Themes Team.
