Hello gonchar,
Thanks for reaching out to us!
To start, let me ensure that I’m understanding the issue correctly. It sounds like you’re trying to change the title for the Event Category section using this option within the Filter Bar settings. However, when you do, the Event Categories no longer display within your Filter bar?
As a first step, can you verify that the Event Categories are selected to display within the filter bar here? Also, could you verify that you’ve completed the Testing for Conflict procedures to ensure that this isn’t a potential conflict with the theme or a plugin?
Thanks!
– Josh
