Azure B2C custom policy - api.localaccountsignup - only some fields are automatically translated

Not sure if the are supposed to be built in, but we have them set up ourselves as well.

This is how you can set you remaining values:

          <LocalizedString ElementType="ClaimType" 
            ElementId="email" 
            StringId="DisplayName">E-Mail-Adresse</LocalizedString>

          <LocalizedString ElementType="ClaimType" 
            ElementId="newPassword" 
            StringId="DisplayName">Neues Kennwort</LocalizedString>

          <LocalizedString ElementType="ClaimType" 
            ElementId="reenterPassword" 
            StringId="DisplayName">Kennwort wiederholen</LocalizedString>


You probably don't need these, but just in case:
          <LocalizedString ElementType="UxElement" StringId="button_continue">Weiter</LocalizedString>
          <LocalizedString ElementType="UxElement" StringId="button_cancel">Abbrechen</LocalizedString>

As a guideline, you can also look for those claims in the TrustFrameworkBase file and by inspecting the fields in your browser using the developer tools. I find this helps me most of the time to find the correct values.
