Stopped using short url

My site was always using the short version url when someone tweeted via the shareThis icons but recently it started using the full website url.
I tried adding “shorten”:true just to be safe, but that didn’t change anything.

My code is

<script charset="utf-8" type="text/javascript">var switchTo5x=true;</script>
<script charset="utf-8" type="text/javascript" src="https://w.sharethis.com/button/buttons.js"></script>
<script charset="utf-8" type="text/javascript">stLight.options({"publisher":"xxxxxx","servicePopup":true,"shorten":true});var st_type="wordpress4.4.2";</script>

<span class='st_plusone_hcount' st_title='<?php the_title(); ?>' st_url='<?php the_permalink(); ?>'></span>
<span class='st_fblike_hcount' st_title='<?php the_title(); ?>' st_url='<?php the_permalink(); ?>'></span>
<span class='st_linkedin_hcount' st_title='<?php the_title(); ?>' st_url='<?php the_permalink(); ?>'></span>
<span st_via='xxxx' st_username='xxxxx' class='st_twitter_hcount' st_title='<?php the_title(); ?>' st_url='<?php the_permalink(); ?>'></span>
<span class='st_facebook_hcount' st_title='<?php the_title(); ?>' st_url='<?php the_permalink(); ?>'></span>
