Problem with multilingual?

Hello,

I have wordpress in French and use WMPL to have an English version.
As I see the plugin works perfectly in the French posts, as it display nothing in the English posts.
fleur : La renoncule bulbeuse/
Flower : Bulbous buttercup

How to solve this issue? By the way, I would like the information to be displayed in English in the English one (it is displayed in French in the French one).

Thank you!
