Multilingual databases

I have question about Notes client settings for multilingual databases. I have set two languages in User preferences - Content language in following order: English, Polish. I wrote Notes application that contains czech and polish design elements. I thought that Notes client have to try use english design and if it doesn’t exist, then will have to use polish design. But after opening in Notes client (7.0.2) czech design is displayed. What is wrong? Does anybody know, how can I display polish design correctly? (I need keep English as primary language in Notes client settings).
