Hi David,
I think using waveform generator as an input will not work on simulating noise analysis, I will verify this. For now, change the input with a universal source and configure it as a sine wave input. Also, under the noise analysis settings change the mode into frequency instead of device. Then try to run the simulation.
As a reference, below is the screenshot of my simulation.

I hope this helps.
