Morgan Dumble pops and scratches

The Dumble SW50R amp in the Morgan Suite makes random audio pops and scratches. The other 2 amps in the Suite are fine. Still happens when all other options off (eq, pedals, cab) No CPU spikes. I’m not clipping. I have 4 other Neural plugins and this is the first time this has happened.

I’m in Standalone mode in this case.

Tried increasing buffer size, no help.

Has anyone seen this?
