Google Analytics registers the product prices over 1000 HUF wrong from my prestashop webshop

We have a webshop running on prestashop, and we are gathering the statistics of the shop on google analytics. The problem is when a product's price is over 1.000 Ft (hungarian forints), somehow analytics divides the price by 1.000. For example if I have a product that costs 3540 Ft, when someone buys it, in google analytics it looks like, it costs 3,54 Ft. The products costs under 1000 Ft are appearing properly. The interesting part is that it only happens with the products, the full price of the orders are correct, it doesn't divide those. I've tried to separate the thousands with commas, dots, or nothing, but it didn't help. Other thing is, in analytics the names of the products are not in UTF-8 (you need it for hungarian language), it looks messed up with all the products.
