Keywords WPML

Hello,

I have a little problem in my website.

I use this plugin: Add Meta Tags – and language plugin WPML.
Meta tags work perfect for main language, for each subpage i create own keywords and it works okey. But if i put another keywords for other language on header i can see keywords standard keywords + keywords from main language.

I want to make just other keywords for other languages.
How can i make it?
