Language

I need help, why when i translate somthing in Dolphin o when i create a new key for a word. All the languages dissapear of the Dolphin modules. When i create a new key, only it is saved in  english . 

Do you know what is the problem and the solution. If i add a external modul(no dolphin) When i want to translate, it does not translate the language and all languages of the other module dissapear to.

where is your existing translation stored?

if you just uploaded lang-xx.php file to /langs folder then it will be erased every time new language key is added, because it restores translations from the database.
