Good evening Arwa and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the venue and map not displaying in your events.
I would love to help you with this topic.
Based on what I am seeing I believe this might be caused by your specific WordPress theme.
This theme has several customizations to our views, including the single event view.
It is quite possible that these views are in need of updates.
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.
As a quick test, you can simply temporarily revert back to a default WordPress theme such as twenty-sixteen and see if the issue persists.
Let me know how that goes.
Best regards,
Geoff B.
