Howdy Marina,
I would love to help you with this.
The best way to do this is by creating a theme override. We have a step-by-step guide for creating those here: Themer’s Guide.
Specifically the file you want to override is /plugins/events-calendar-pro/src/views/pro/modules/meta/additional-fields.php . On line 18 you will see the
that outputs the other title:
<h3 class="tribe-events-single-section-title"> <?php esc_html_e( 'Other', 'tribe-events-calendar-pro' ) ?> </h3>
You can rename it from there.
Does that all make sense? Will that work for you? Please let me know.
Cheers!
