[Plugin: The Events Calendar] List View Pagination Not Working

i’ve got a site and i’m using [Plugin: The Events Calendar] to generate both a list view and a grid view – the list view page works, but when i use the pagination code (unedited from the plugin), the URL goes from:
/category/calendar/upcoming/

to:
/category/calendar/past/

i have more than 1 page of upcoming events, so i want it to show the second page of events, not the past (which there are none). the logic here seems like it could be wrong, but i’m not sure how:

<div class="nav-previous"><?php
	// Display Previous Page Navigation
	if( events_displaying_upcoming() && get_previous_posts_link( ) ) : ?>
		<?php previous_posts_link( '<span>&laquo; Previous Events</span>' ); ?>
	<?php elseif( events_displaying_upcoming() && !get_previous_posts_link( ) ) : ?>
		<a href='<?php echo events_get_past_link(); ?>'><span>&laquo; Previous Events</span></a>
	<?php elseif( events_displaying_past() && get_next_posts_link( ) ) : ?>
		<?php next_posts_link( '<span>&laquo; Previous Events</span>' ); ?>
	<?php endif; ?>
	</div>

	<div class="nav-next"><?php
	// Display Next Page Navigation
	if( events_displaying_upcoming() && get_next_posts_link( ) ) : ?>
		<?php next_posts_link( '<span>Next Events &raquo;</span>' ); ?>
	<?php elseif( events_displaying_past() && get_previous_posts_link( ) ) : ?>
		<?php previous_posts_link( '<span>Next Events &raquo;</span>' ); // a little confusing but in 'past view' to see newer events you want the previous page ?>
	<?php elseif( events_displaying_past() && !get_previous_posts_link( ) ) : ?>
		<a href='<?php echo events_get_upcoming_link(); ?>'><span>Next Events &raquo;</span></a>
	<?php endif; ?>
	</div>

suggestions? you can see the plugin/site in action here: https://sideout.230.ca/category/calendar/
