I think you need custom view for the enum field (status), it can be as following:

 Espo.define('custom:order/fields/status-field-name', 'views/fields/enum', function (Dep) {     return Dep.extend({          afterRender: function () {             Dep.prototype.afterRender.call(this);              this.model.on('<dateFieldName>:change', function () {                 this.model.unset('<dateFieldName>');             }.bind(this))         }              }); });
