Service control events messages

Hi,
While trying to track down a rise in messages in our azure servicebus queues, I noticed that there seems to be a number of messages in particular.servicecontrol.prod.events topic. I can’t find anything in that topic when I look at it with QueueExplorer. Are they hidden? Report glitch in azure?


Filtered for particular.servicecontrol.prod.events

Blue is total message count, red is scheduled.
Thanks,
Nate
