Azure Diagnostics VM Extension: Not collecting .NET Event Source events

I've enabled the Azure Diagnostic Extension on an Azure Windows VM in the Monitoring > Diagnostics settings section of the VM.

I've enabled Event Tracing for Windows (ETW) events as follows:

Event Tracing for Windows ETW > Enabled

DG-AP-QA-Testing - Verbose

MyCompanyEventSource - Verbose

And I've set them to store them in the following storage account:

I'm running a simple console app on the VM that writes some events to the sources specified but nothing ends up in the storage account.

Using the Storage Explorer, these are the tables it contains, but none of them have any of the events I wrote using the .NET EventSource class.

What's the table name that it should collect ETW events? What can be the issue causing them not to be collected?
