There's a setting from one plugin (Types) that Polylang has on strings translations which purpose is only to be used at new/edit post screen at backend.
I have my backend also multilingue using WP Native Dashboard plugin and of course that new/edit post screen changes according the language.
This particular setting from Types plugin is a field validation error message that shows when users input for example text in a numeric field or leave blank a required field.
This meesage is handled by an Ajax function belonging to Types plugin, as the user types the wrong data the message pops up.
Despite Polylang has it as a translatable string, it never gets translated because it is only used at backend.
Can Polylang filter this one to make it translatable?
