Admin config value not updating to match database value

Updating value with configWriterInterface updates value in the database, but does not carry the value to the admin. When trying to call the value later with scopeConfigInterface it returns the value from the admin field, not the database.

What am I doing wrong?

 /**
 * @param MagentoFrameworkAppConfigScopeConfigInterface $scopeConfig
 */

 public function __construct(
    MagentoFrameworkAppConfigStorageWriterInterface $configWriter
) {
    $this->_configWriter = $configWriter;
  }

  $value = 'newvalue';
  $this->_configWriter->save('carriers/testship/name', $value);

Value in the database:

Value in the admin:

If I call the value from scopeconfiginterface, I get the Admin value.

// get the Object Manager
$objectManager = $bootstrap->getObjectManager();
$scopeConfig = $objectManager->create('MagentoFrameworkAppConfigScopeConfigInterface');
$value =  $scopeConfig->getValue('carriers/testship/name',  MagentoStoreModelScopeInterface::SCOPE_STORE);
echo "value: ".$value."n";

value: oldvalue
