Custom Product Pages not working in some language variations

Hello, We have created several Custom Product Pages for our app in all language mutations we have. As we are planning to use them in our propagation, we have tried to check them on web and in the App Store, too. Half of them is working correctly - I fill in URL, change the localization and my CPP is shown. Other half totally ignores settings and displays English versions of CPPs. The most I have got from this is change to default store page in correct language by settings in the footing of the page. And as you can guess, I don't want neither, I want the CPP I had worked on. Does anyone have similar experience with Custom Product Pages not displaying correctly in any language? Is something I can do to correct it?

Thanks all
