The equalizer on the muted track distorts the sound. How can this be?

[Anatolio]

I came across the fact that the Pro Q3 on the off track distorts the sound of another, active track. Distortion occurs when using the "linear phase", while turning off the Pro Q3 plug-in does not help, it is necessary to activate /deactivate the plug-in, the only way you can hear the original sound of the active track.

Why is this happening? I'm at a loss. I know that the linear phase requires resources and the delay accumulates. Because of this? I've never come across anything like this. Why does the effect occur even if the Pro Q3 is on the off track and even if it is turned off (in the video I deactivate, it is not off)
