Problem with displaying 2 prices

Hello.
I have a problem when I try to display 2 prices on my web store.

I’m using WPML for slovenian and croatian store language. The WPML itself has integrated WooCommerce Multilingual & Multicurrency plugin. And if I enable your plugin and set another exchange rate the prices get x3 of the prices that should be.

Is there any instructions on how to set the plugin so that it would ignore exchage rate and just display both prices.

On slovenian language ony prices in € should be displayed but on the croatian site both € and Kn prices should be visible.
