Actually, when we inspected in our side, everything is working fine as you can see in screenshot below:

Also, third party plugins conflict can be one of the leading cause for the uncertain behavior of your site. So, please verify the issue by deactivating the third party plugins one by one.
Further, make sure that the dates of post are different and the theme you have used is of latest version.
If issue still persist, please provide us with your admin login detail in below given email:
