Good evening Maruf and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
I would love to help you with this topic.
As a first troubleshooting step, could you please provide us with your complete system information in a private reply using the instructions found in the following link?

Secondly, by the looks of it, it sounds like there is a template customization on your site.
In other words there is something in your theme that changes how items are displayed (compared to the default view).
You might want to read our Themer’s guide to get a sense of how that works.
Could you please send me a copy of the latest version of your WordPress theme / child theme via a link to a .zip file link (stored Dropbox or Google Drive) so that I can run some tests on my end ? I recommend a private reply for that purpose.
Please ensure you are using the latest files as found on your actual website.
This way I will get access to any updates or customizations you might have made.
Hang in there!
Geoff B.
