Hello Jacquie
The best way to get help for your theme will be to reach out to your theme’s support. Unfortunately, that is beyond our Scope of Support / Terms.
To fix the width of your featured image events, add this CSS code. I like to put it in Appearance » Customize » Additional CSS, but if your theme supports adding CSS, add it there if you like.
.tribe-events-list .tribe-events-event-image+div.tribe-events-content
{width: 100% !important;}
.tribe-events-list .tribe-events-event-image
{width: 100% !important;}
Normally this does not happen. I suspect it might be a theme issue, but the code should override the conflict.
Let me know if it works for you.
Thanks,
Courtney 🙂
