PDF functions don’t work on second language

Hello,

I have a question regarding plugin. I am using plugin on my WP 5.8 version and I have 2 languages on website supported with plugin TranslatePress.

My primary language is Slovenian and second language is English. The issue is that on Slovenian site the PDF can be created but when you switch to English version it can’t create the PDF, plugin used for this is WooCommerce Print Products (PDF) (https://codecanyon.net/item/woocommerce-print-products-pdf/14890964). I spoke with their support but they said that issue is with TranslatePress plugin.

Example if issue:
Slovenian product: https://fistrucks.com/izdelek/man-tga-26-350/
Same product but English: https://fistrucks.com/en/product/man-tga-26-350/

When you click PDF icon it can’t create it on ENG site but works on SI site.

Thank you in advance.
Br, Alja?.
