Issue with WPML

We are using this module and everything was working like a charm for a while. After installing WPML we encountered strange issue. If I go Multi Rating->rating result i see all different posts. No duplicated post or what so ever. Then if i choose “All post/ pages” there are multiple choices with same name. Duplicates will appear only if i use this filter and they have different ID. They have their own rating as well (will increase if i rate something using different language and duplicate will be added if i use our second language in frontend). So, it is probably related with WPML, but our client is confused. Is it possible to merge those results.
