currency don’t switch on product details

Hi, the currency does not change when I try to use it on each product detail tab, for example here: https://www.100one.pl/produkt/flansza-wydechu-mini-cooper-audi-rs3-2-5-tfsi-8v-2014-227/

I have to go to the home page, change the currency and then go to this product again and then there is the currency changed. On the product page there is no chance.

The page I need help with: [log in to see the link]
