We found this extremely frustrating too. We found ways to edit the event page but it is very limited. You can try playing with this setting: wp-admin > Events > Settings > Display tab > “Events template” option — to see if changing it makes things work better for you. However, the ticket bar (which is extremely ugly) still didn’t go away. So, we ended up creating our own event page with divi and linking tickets to the custom add to cart button. It’s not a great solution but it works.
