All Language Flags Activated on Non-Translated Pages

All Languages flags are shown in pages despite not beeing translated to all languages. Example: This one is OK! https://trisquel.info/en/wiki/configure-2d-and-3d-graphics-acceleration But this one is wrong https://trisquel.info/es/node/10974

On those non translated pages but with all flags "activated" you're shown the English version (the original) by doing click on any flag.
