Different quotes in different languages

Hello,

I’d like to have different quotes in different languages but it does not seem to work.

When I try to change the quotes in the second language (add one and delete another one), the fields are gray and I can not touch them. So, I’m stuck with the quote put for the first language. What do you think it could be? The quote feature could be not set up for the second language you think?

Thank in advance for your help.
