'Game Piece Palettes' : any troubles with translation ?

Hi all,
I build a module in english and I’m translating this module in french (my native language).
I set the language for the translation to “French/Any country”.
I also set the preferred language in Vassal to “French”.
In “game mode” : everything is translated , except within [Game Piece Palettes] where there are any problems…

the module :
dropbox.com/s/ljtilp0l1wtha … 2.zip?dl=0
