String not translated when validation failed in modular blueprint

hi,

I have a template with specific modular blueprints, my form have translation string and i have a languages.yaml file wich contains all translation, so it works great, all string are translated. The issue is when there is a validation rule, see screenshot

I have :
Validation failed:
Invalid input in “THEME_ELANA_FAQ_ANIMATION_DURATION”

But “THEME_ELANA_FAQ_ANIMATION_DURATION” is translated in my blueprint.

So i don’t understand
Thanks for any tips

Is this Grav 1.1? Should definitely work, the code looks for a translation string

yes Grav 1.1
