wrong another language price

Hello, just one question.
The plugin is great, feeds are generating quickly.
There is just one little problem we cannot get hand on. When generating feeds in another language and currency, for just a few products, the price remains in default currency. For example we have Croatian and Slovenian feed.
In Croatian, product has 999 HRK price and in Slovenian it stays the same 999 EUR. We are using WPML and EUR price is being calculated.
That happens for very very little amount of products but it does. In Google and Facebook feed. We cannot see why. Products are simple not variable and products that this is happening are the sme as all others.
Any idea? Thank you in advance, with regards.
