How do I translate Field Group labels? I have two field sets

In the admin/config/regional/translate I have translated the &quot;Account settings&quot; label

What can I do to translate the field group labels?
Field groups are configurations which are not translated via the translation interface. I am quite sure that the string &quot;Account settings&quot; that is translated in your project does not come from your field group. Just change the label of a field group to any other string - you will not find the string in the translation interface.
You need to activate the &quot;Configuration Translation&quot; module.
