Capturing the noise print works. Audibly, the Noise Reduction (Process) does as well. However, the VISUAL waveform is buggy and not changing across the entire timeline. It very clearly works at the location where the noise print was captured, but the waveform of the Noise Print gradually increases across a radius of about 60-90 seconds if you're applying the Noise Reduction across the entire timeline, at which point it looks like it did not work at all -- even though it does when listening back to it.
