Hi Callum!
Thanks for reaching out to us. Let me help you with your issue.
I could not reproduce the issue you are having, so this could be a theme or plugin conflict, so to narrow the problem down please go through the steps provided in the testing for conflicts guide > https://theeventscalendar.com/knowledgebase/testing-for-conflicts/ and let us know what you find in the process.
Also, make sure you are using the latest versions of our plugins as these might include bug fixes that can relate to your issue.
We suggest you setup a dev/staging site so you can make all these tests without disrupting the live site. We also encourage to make a full <u>backup</u> of your site, both database and files so in case something goes wrong you can always restore your site.
Let me know how that goes.
Thanks,
Victor
