Woocommerce filters not showing

I have an issue with my woocommerce filters.

The price one shows an error “There was an error loading the content. Error: Cannot read properties of undefined (reading ‘Label’)”, and the two other filters simply doens’t show up at all.

Here is the page in question : https://staging2.ateliermauny.fr/shop/
(or any product listing pages anyway)

I isolated the issue coming from Siteground plugin Speed Optimizer.

I tried to exclude following scripts related to woocommerce on the plugin (in Frontend > Javascript > Exclude from Deferral & Exclude from Minification :

  • /plugins/woocommerce/assets/js/jquery-blockui/jquery.blockUI.min.js
  • /plugins/woocommerce/assets/js/frontend/woocommerce.min.js

I also found out an error on the console, as you can see on following photo :
