Hello,

I think the issue is coming because of the 3rd party plugins, please deactivate all the 3rd party plugins from the site and activate only theme-required plugins on the site, I am sure your issue will be solved.

Also, please check how it works with the default WordPress theme just to check whether the issue is with our theme or not.

If the problem continues then leave the plugins deactivated and tell me then we will troubleshoot with default plugins.

Best Regards.
