I've got a development site running using Drupal 8.7.7/Civi 5.17.5 and CiviCRM Entity. I want to set up some Views to display Civi data. Some fields are being displayed fine (e.g. first name, last name), but other fields from the contact record appear to be empty, when I know, by looking at the CiviCRM contact records, that these fields are populated.
As an example, I want to display the Birth Date field. I have nearly 200 records where this field is populated.
If I look at the CiviCRM Entity display of the contact record (e.g. www.example.com/civicrm-contact/xxx (where xxx is the contact ID) I can see some of the fields in the contact record but not Birth Date, despite the fact that www.example.com/admin/structure/civicrm-entity/civicrm-contact/display indicates that this field is not disabled.
How can I get CiviCRM Entity, and Views to display this field correctly?
