V 7.1.7 CUSTOM TRANSLATION Language Code only "EN"

As my home language i use spanish and custom translations for making the fields more easy readable to users, but i notice as ver 7.1.7 that all new translation i create are defoult in ENGLISH language code and cant be modified to other language. Any Help?

Can you share some screenshots please.

sure as you can see my base language is es (spanish) :

But al new translations are in english only and the field is read only

Change the default language in customize translation form. Insert you language code, in my case “it”
Now… ctrl+r ctrl+r ctrl+r
Language is now change. Insert translation source in english.
Work for me

Translation is not based on User Language, it is based on the language set in System Settings.

That did the trick. thank you!
