OK, so can you try adding this snippet to your theme’s functions.php file? This should place the title in the grey or “striped” area as it is when other posts/pages display in your theme.
Do note that this also means the title will be duplicated slightly lower down. To get rid of this second title you could override the relevant templates and simply comment out or delete the relevant line.
In single-event.php for instance this looks like:
<?php the_title( '<h2 class="tribe-events-single-event-title summary">', '</h2>' ); ?>
And in month/content.php it looks like:
<h2 class="tribe-events-page-title"><?php tribe_events_title() ?></h2>
For an overview of theming and template overrides in general, please see: https://theeventscalendar.com/support/documentation/events-calendar-themers-guide/
Does that help?
