For anyone else searching, my issue was resolved. The following response was given by ShareThis support.
We have checked your site code and observed that you have added same URL in the SPAN tag code on all the pages. That means you have same copy of code on all the pages and hence they are showing the same count.
<span class=’st_facebook_vcount’ st_title=’Jobs’ st_url=’https://www.tefljobsworld.com/development/jobs-2/’></span>
<span class=’st_twitter_vcount’ st_title=’Jobs’ st_url=’https://www.tefljobsworld.com/development/jobs-2/’></span>
<span st_title=’Jobs’ st_url=’https://www.tefljobsworld.com/development/jobs-2/’ class=’st_email_vcount’></span>
<span st_title=’Jobs’ st_url=’https://www.tefljobsworld.com/development/jobs-2/’ class=’st_sharethis_vcount’></span>
If you want a unique count for each job page, either remove the “st_url” property –
“st_url=’https://www.tefljobsworld.com/development/jobs-2/”
from each SPAN tag code, or add the unique job page URL.
Please note that if the “st_url” property is not present, then the ShareThis buttons shares the page URL on which they are present and the counters shows the unique count for that page only.
Hope this helps and clarifies.
Also, it seems that you tried to add the code manually to your site and hence multiple wrong instances are present, please remove them. Shown below –
<script type=”text/javascript”>var switchTo5x=true;</script>
<script type=”text/javascript” src=”https://w.sharethis.com/button/buttons.js”></script>
<script type=”text/javascript”>stLight.options({publisher: “ur-e3da3210-bd0-54c3-99b6-43b0f0daaca0”, doNotHash: false, doNotCopy: false, hashAddressBar: false});</script>
