Hi Alican,
We are really sorry to say that the behavior of the template is normal when you resize the browser, it’s not an issue.
Because responsive means using responsive devices like mobile, tab, etc. If you want to check the responsiveness of the template then you need to use responsive devices. Or if you want to check the responsiveness by resizing the browser then you need to reload the page.
Best Regards,
