Hello, Fnhc,
Thank you for your response.
As we can see, it works fine on the Cart page, but not in the Off-Canvas cart.
Please download functions.php file from this page – https://we.tl/t-4OWYyUUWhc and reupload it into plugins/et-core-plugin/app/models/customizer folder via FTP.
Clear cache and check the result then.
Kind Regards,
8theme team
