Hi, Michael!
Thanks for using The Events Calendar! I can help you with this 🙂
To change the title of any of the filters in the Filter bar head to ‘Events > Settings‘ and go to the ‘Filterbar‘ tab.
From there you can click the dropdown for the filter you want to change. You’ll see an input box with the current title and that’s where you can make the changes you need.

Click ‘Save Changes’ and you’re good to go!
Does this help answer your question? Please let me know. I’m happy to help 🙂
Cheers,
Trisha
