Spectral delete nibbles audio sound

[Sherry.81]

I am applying spectral delete to places of hum, stammering, rumbling, whiteboard squeaking.
I face a problem of sound nibbling here after applying spectral delete although I try to leave some of the surroundings energy from the bottom of the wave in that I don’t delete the whole wave but instead I leave some of the waves to enable natural noise.
But there are places where I need to completely delete the wave when I delete the spectrum vertically . So is there a way to repair this sound nibblingstrong text or breaking because the audio becomes
unsmooth ??
