Hello Dee,
It may be caused by your custom CSS you wrote in Theme Options → Additional CSS → https://prnt.sc/BiQMqO7ve086
Could you please, check now? We commented few most “critical“ css that could make such an issue.
Also, you can check if you have such a problem on our demo, in case there is everything ok then it is a local issue caused by your CSS customizations or some other settings made on the website.
Kind Regards,
8theme team
