Audio>Realtime>Flatten - not always sample accurate?

Hi - I have a short period of audio (about 6 seconds) I am applying VariAudio to. No prob until I flatten it - when I play the flattened and unflattened pieces together, there is phasiness.

It’s just on one segment of many - the others, all about the same length, don’t phase at all. Listening to each individually, I’m not able to tell the difference - it’s very slight.

Has anyone noticed anything like this?

Thanks -

Gonna bump this up, in case someone new sees it that might have the same problem -

Thanks -
