Problem with translation

I have faced with a problem for translation. This problem was not before. And I don’t no what coused the problem. I created site with four languages. Then later I had to make one page else. I created the page for russion and than I created translation for english language. But the problem is that english content is on russion page too. And now, for example, if I create translation for germany language this content is on each page, no matter of translation.
How can I resolve the problem?
