isso comment sorting not working

[leadplasticmold]

Hello! First, love isso. Thank you to the creator and all who support it. Second, I haven't been able to get isso's comment sorting option to work for me. No matter what I enter for data-isso-sorting the comment sorting doesn't change. Here is what I have in my script block for it, which is from here https://isso-comments.de/docs/reference/client-config/

<script data-isso="https://deathisso.deaddeaddeath.red/"
src="https://deathisso.deaddeaddeath.red/js/embed.min.js"
data-isso-css="false"
data-isso-sorting="newest"
data-isso-avatar="false"
data-isso-vote="false"                                             
 ></script> 

Does anyone know why it's not working?
