Customers import: some fields are not imported or showed empty

Hello,
customers are imported into wordpress and woocommerce but some fields (phone, country/region) are shown empty in backoffice – user edit.
In woocommerce customerslist some coluns (postalcode, city, region, phoene, country/region) are are shown empty. When enter in edit on a user and just save without edit enything, postalcode, city and region, will be shown in woocommerce customer list. Phone and region it seems they are not imported

thank you in advance
