Thanks for your patience!
Based on your description, there is something odd on your configuration, and I am not sure if this is because of your Azure platform. The scripts and console do have something difference from what I know from Windows OS platform. In this case, I would suggest you to contact our Microsoft Customer Support and Services directly. Our senior engineers can not only offer you advanced technical support but can give you real-time troubleshooting remotely. In this sense, they can get a deeper insight over your environment and current configuration, which can hardly be realized in our forum (we cannot do log analyzing and real-time remote operation). In addition, if the issue has been proved as system flaw, the consulting fee would be refund. You may find phone number for your region accordingly from the link below.

You can also try to re-create your MSMQ role, while I can only find articles for creating MSMQ role on a Windows SQL cluster. I am not sure if it is also applied for Azure platform. Besides, if you find the re-creation is not helpful, you may still have to call our senior engineers.
