Bug description
I have a website wich has 3 main sites and those sites have sub languages.
Like this:

When i am on the main site "/nl" and i submit the form i get the validation back from the nl folder. But when i go to a sub site "/nl/en" which has the english version of the contact form i just get the validation back from the nl folder not from the nl-en folder
here are my lang folders

How to reproduce
- set up a multi site (make sure you have a main site "/nl" and subsites "/nl/en")
- set up validation rules in lang folders for those sites
- create a form
- let the form fail
