Thank you for contacting us.
We already have already logged a similar PITS issue
. I updated it a little bit to match and your case. You can vote for it to increase its priority and track its progress. For now the only way I can help you is to provide you with a simple workaround. Just don't delete the "Title" field and use it as an additional identifier for your items. That way you can have one field used for URL generation and another field (the title) that is used as an identifier when you have to select one particular item to be shown in the widget. Also make sure to remove the "Title" field from your templates so that it is not shown in the frontend and it is used for internal purposes only.
I apologize for any inconvenience this is causing.
