Joomla 4 Testing - Upcoming Event Menu does not display any events

I am just starting testing on Joomla 4 and I have a really strange problem.
I have created a brand new Joomla 4 site and installed Events Booking  4.3.0
I have created some events for testing all with Public Access and registration.
I then create a Menu Item Upcoming Events - Table Layout and selecting the category of the events I have created..

When I display the Menu Item on the front end, all I seen is the Category Description and message ' There are no upcoming events'

I also tried a 2nd category of events where I have test events in the category, but still the same problem 

I also tried creating a menu Item 'Event Details' , but when I try a select an event from the drop down, no events appear!!!!
This is really strange as there are events??
I am really lost as to what the problem is.
Some screen shots are attached to show the problem
