Noise reduction has no effect the first time

[aarnimation]

Build 10.1.1.11, macOS Sierra v 10.12.6

I'm doing Noise Reduction the same way I have for years (capture noise print, select entire track, Noise Reduction), but for the last few months it has only worked when I run it twice, if that makes sense. The first time through does nothing, and I go through the process the exact same way and then it works like I expect it to.

Anybody else bumped into this?

Not me on Windows 10 and this is the first time I've read about it on this forum.

Hopefully a developer will wander by and give us some thoughts.

Are you capturing the noise print from within the NR effect's panel or from the Capture Noise Print menu option before opening the NR effect's panel?

Just using the keyboard shortcut (Shift+P).

In that case, just as a test, try opening the NR effects panel first and then doing the Noise Print Capture from within the effects panel. See if it works OK first time by that method. I vaguely seem to remember a bit of a bug at one stage where the default settings of the FFT size could cause the first external NP Capture to fail until the FFT size (or whatever parameter it was) had been set to a more suitable value.
