Translation WPML not working entirely

Greetings,

First i would like to say your plugin is really helpful and i really want to stick with it fully, but i’m having a big issue that prevents me on going.
Our website have 2 languages, english (primary) and portuguese.
When i use it in english, all the products are shown accordingly to the specific categories but when i go to portuguese, only the products with the same name in category works. e.g. T’Shirt or Flipbelt. Other options just don’t apepar even though it’s there.

Regards,
John
