Thank you for your feedback.
I have double-checked these on the Microsoft Language Portal and replaced the strings. The only difference with the strings you provided is that I used "Niveau inférieur" for the RibbonWindowRestoreDown value.
These changes will be available with our next internal build which will be introduced next Monday (02.12). As a thank you for bringing this to our attention, I've awarded you with some Telerik points.
Please let us know if you come across any other inaccuracies or if you require any other assistance.
