Hello, @sk,
I have just checked your site and debugged it deeply and found that the Menu item with which you are facing the issue, is not our theme item, It’s actually the WordPress core option. If you check your site by activating the default WordPress Theme like Twenty Twenty Two, you will find the same option and same behavior on your site, you can try to test it.
And then you have to contact WordPress support on it as this is a WordPress core issue, not our theme issue.
Hope you can understand our limitations.
Regards 8Themes Team.
