This is expected. The CSV import form uses a period to separate a field name from its accessor (e.g. site.name).

You shouldn't be using punctuation in a custom field name to begin with, though: Stick to alphanumeric characters for the field name and specify a separate label for the field if you want to display something more human-friendly.

But this is something new. In previous releases imports with .) worked fine. Of course all headers and values are in quotes "". Is there any workaround to use custom field with . in name?
