Can't create language specific redirect if there is "All languages" redirect defined for the path

Hi,

If we are creating redirects from the path "test" for several languages (English, Italian, French) it all goes fine and we end up having 3 redirects for every language pointing to language specific URLs.
Then we define the "All languages" redirect for the path "test" to have the default redirect for this path. And after doing this we are not able to define more language specific redirects for this path (Spanish, Japanese). But if we remove the "All languages" redirect - then we can add more language specific redirects and then add the "All languages" redirect back.

Looking forward to resolution :) From what I understood, it is somewhere in the path_redirect_load_by_source function logic used in the form validation.

Thanks
