Good evening David,
You are right!
The issue is that this section of the page is generated by the $time_formatted variable defined in /wp-content/plugins/the-events-calendar/src/views/modules/meta/details.php at line 25
The simplest way to tackle this would be via a template override of that file. You might want to read our Themer’s guide to get a sense of how that works.
Basically, remove the end time from that variable, upload the file back in the correct folder in your Avada Child theme and you should be good to go.
Let me know how that goes.
Best regards,
Geoff B.
