Hi Sven,
So if I am understanding you correctly and you wish to remove the event description from list view, the first step is to review our Themer’s Guide which explains how to safely override and customize our templates.
With that done, you’re probably going to want to customize the list/single-event.php template. Simply find and locate the following lines of code:
<!-- Event Content -->
<?php do_action( 'tribe_events_before_the_content' ) ?>
<div class="tribe-events-list-event-description tribe-events-content description entry-summary">
<?php the_excerpt() ?>
<a href="<?php echo tribe_get_event_link() ?>" class="tribe-events-read-more" rel="bookmark"><?php _e( 'Find out more', 'tribe-events-calendar' ) ?> »</a>
</div><!-- .tribe-events-list-event-description -->
<?php do_action( 'tribe_events_after_the_content' ) ?>
Does that help?
