Apologies for the inconvenience caused. I’ve discussed the issue with our development team, and we’ve identified a problem currently affecting the Mega Menu functionality.
As a temporary solution, after adding a new menu item, please open the Mega Menu settings and simply click "Save." This should ensure the new item displays correctly.
We understand this is not ideal, and please rest assured that our team is actively working on a more permanent fix, which will be included in an upcoming update.
Thank you for your patience and understanding.
Best regards
