Good evening Gavin and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the title of the page not working as expected on your site.
I would love to help you with this topic.
Sometimes this type of issue can be caused by SEO plugins (but it does not look like you have one in place).
The second most common cause is how some WordPress themes handle WP archives (which our plugins use extensively). I believe this is the case here.
The first thing I would recommend is trying out different settings for Events template under Events -> Settings -> Display to see if that helps.
If it does not, could you please send me a copy of the latest version of your WordPress theme / child theme via a link to a .zip file link (stored Dropbox or Google Drive) so that I can run some tests on my end ? I recommend a private reply for that purpose.
Please ensure you are using the latest files as found on your actual website.
This way I will get access to any updates or customizations you might have made.
In the meantime, you might find the following useful: https://theeventscalendar.com/knowledgebase/altering-or-removing-titles-on-calendar-views/
