French auto-correct

I’m currently using the beta version of scrivener for windows and I have some problems with the auto-correction module.
I’m French, so I downloaded the French dictionary for scrivener.
But, despite this, the correction is far from being efficient, and the “correction while typing” system often chooses the wrong word.
The strange thing is that this problem didn’t exist on scrivener 1.9 where the auto-coorect was working perfectly.

Do you have any information about this.

Thanks for your work.
