Hi Chanel,
I’m sorry that you’re running into this issue, but I’ll be happy to help you out!
I tested this out on my end, but I haven’t been able to recreate this locally. As a first step, can you try adjusting the “Default stylesheet used for events templates” and “Events template” settings under Events > Settings > Display. These affect how much events pages inherit their styling from the theme.
Next, can you run through the steps outlined here to check for any conflicts that might be occurring with your theme/another plugin? You’ll want to make sure you drop down to a completely default environment (the Twentyseventeen theme enabled and all plugins besides The Events Calendar and Events Calendar Pro disabled) to begin testing, with WP_DEBUG enabled.
Please let me know what you find!
Thanks,
Jennifer
