It may come from the fact that the strings are created by Types before Polylang sets the correct language. If, in Polylang settings, you set the language from the url, the language is set sooner than if you set it from content. However even, in first case, it may come too late. I paln to improve this in v1.1 and load the language as soon as possible (as WPML does), but it will be possible only when setting the language from the url.
