Unfortunately Mr. Trebor, the suggestion doesn’t work. I inserted a segment of silence to test.
I have been using Reduce, not residue.
Following your values 6,6,6 for Noise Residue, I applied, as the Screenshots before and after would illustrate.

The same effect with Reduce.
Clearly, the tool fails, Mr. Trebor. Worse, it splits the audio into two halves.
When I posted my observation, I have been using Reduce, not Residue.
Is the Tool damaged? Is it possible to install the Tool separately, Mr. Trebor?
