Help with Audio Problem

Hey, I’m a radio producer here in the States and I have a particular challenging problem that I don’t know if there’s a fix to. Anyways, when I recorded this audio, this problem wasn’t showing. Not even in the spectral view. I don’t exactly know what happened. But beyond using the spot brush tool for the whole show (this is only a part of it), which would be extremely laborious, is there an easier fix to my problem here? Any help would be appreciated. Thanks!
