This means StockSubmitter did not submit this image.
If you submit images manually, either insert correct title in the field or check "Upload only" checkbox in CreStock settings in StockSubmitter.
Automatic submission to CreStock is unreliable at the moment because of technical limitations on CreStock side. We tried to negotiate a reliable way to submit images but they do not want to collaborate regarding that. So if it does not work for you, you can check "Upload only" checkbox for CreStock and submit images manually.
