Cubase 12 Drum Editor: Note Names Don't Sound

Using Groove Agent this morning. I loaded up a kit and have the drum map installed.

When I click on the note names, the drums will only sound 1 to 3 x’s before going completely silent. Then, I have to shut down the editor and reopen it to get the note names to sound again. But, it’s the same every time. Dies after sounding 1 to 3 drums. Acoustic Feedback is enabled.

Anyone else seeing this?

I had my browser open in the background, and for some reason it was interfering. I shut it down, and everything is back to normal.
