Translating issues

Hi! In order to have a multilanguage website (GB/FR) I used Polylang. On the homepage everything can be translated except Front Page Header Content: title, subtitle, label. Basically I get a new page in French with main header texts in English (as the main language). What can I do to have everything in French? (I tried to manually change the texts in the Front page Header Content, but it doesn’t work). Thx!
PS: I would glady buy the pro version if this works. Also it would be useful on your demo site to have an example of a multilanguage site (frontpage included)
