Translation of Fields

I Would like to translate fields with the translation register. Now the fields in the translation register are not editable anymore. How can I enter translations for field names?
Thanks and cheers

there has been a change in how you name field and also maintain their translations.
The fields are linked to elements which can be renamed or translated.
The idea is to keep the name of a field e.g. created the same throughout the whole application.
So when you change the name of an element it will automatically inherited to all fields linked to it.

From Window Management - Tab Field => Zoom into related element and change the name or translation
