Hi Chan,
Thanks for getting in touch and sorry to hear about this issue, I’ll help you getting it right!
First let me tell you that the current version of The Events Calendar is 4.0.5, so maybe it’s a good idea to update to the latest version before fixing any issues. Do you agree? Is there a reason why you won’t like to update our plugins?
In case you are up to updating the plugins please share your system information with me so I can see which plugins you are using and send you over some advice on the update.
Regarding the title issue I’m not sure about what’s happening maybe you can send over a screenshot of the site (you can use cloudup.com or similar services to upload the images and share the URL here)? Please check these two articles, maybe they address your issue: Altering or removing titles on calendar views and Changing the browser title for calendar views.
Please let me know about it,
Best,
Nico
