Fields Not visible in other languages

Hi, I’m using WPML and each lang, points to different domains….
If I set the ppom field at Product level, It only appears on the original languages (even if all strings are translated)
As a work around, I’ve set the fields to appear at Category level (which I don’t want) and even doing this… I have to set the same category in every language available to make it work….
Is this the way it’s supposed to work?

Thanks
