This thread is resolved. Here is a description of the problem and solution.
Problem: Categories are mixed up with different languages Solution: Edit. The issue was with WPML settings. I did setup it so if there are no translations it will fallback to default language(under taxonomies translation). So as the categories are all with unique ID and are no translation to each other, then it showed EN language as well because it assumed the category has no translation.
