Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
We checked your page and we can also confirm the meta title is properly added on there without the site name. That means there is nothing wrong with your settings.
Nowadays, Google does that very commonly. Even when everything is fine, Google may choose to display a different meta title for your search query result. Google may skip the custom metadata you have set and instead display something from the page’s content that better matches the search intent.
You can follow this URL for details on this issue:
