Conflict with Ultimate Member and User Role Editor

I’m currently using Ultimate Member for frontend login/registration. I’m trying to allow users to delete their own posts on frontend with following code:

					<?php if ($post->post_author == $current_user->ID) { ?>
	                    <div class="col-sm-12 box-delete" style="margin-top: 20px;">
	                        <a class="option" onclick="return confirm('Are you sure you want to delete <?php the_title();?>')" href="<?php echo get_delete_post_link( $post->ID ) ?>">
	                            <i class="fa fa-trash"></i>
	                            <span class="option-text">Delete</span>
	                        </a>
	                    </div>
					<?php } ?>

I’ve installed User Role Editor plugin so that I can allow user to delete_published_posts, however only works when I deactivate the Ultimate Member plugin. Any idea what issue is and how to resolve?
