Date format not supported

When we add a date with the date picker, it shows $.($.(ReviewPages.ReviewData).().(nextReviewDate).().()) instead of the date. Then it will not be possible to save : Date format not supported.

Same behavior with the 0.1 version.

I tried to specify a date format "yyyy/MM/dd" in the admin panel and change the language to english (french by default).

I remember that this extension works well with a 7.xx version when we tested xwiki. We are now in production on a 8.0 and would like to use it.
