Conflict with Template design align with Demo

I hope all is well.

My current events template: https://ilovefreeconcerts.com/events/

Template I desire (Demo): https://demo.wp-events-plugin.com/events/

My first thought upon downloading this plugin my template would mimic what the Demo looks like, but I was completely wrong.

– How can I go about fixing this problem ? I want to try this out and get the write coding involved before I purchase premium account.

Thanks
