I am following you instructions on setting up a Membership section on a new website. Native language is Danish.
The Toolset 'User Login' function dos not translate correctly, as 'Username or Email' seem to be hardcoded English instead of picking up the System Language as does the other fields. Please consult the enclosed screenshot. The correct wording in Danish would be:
Brugernavn eller E-mail
Will most likely influence all other languages as well.
