Well, to fix something like this one would need to know the nuts and
bolts of one's filtering system. Where would you put this
'short-circuit' if the whole machinery has become too complicated for
one person/team to tame?
Especially now with people adding AI to everything and not understanding
any of its internal workings, I'm not very optimistic for the future of
anything requiring proper tuning. We're just training whole fields to
trust a result just because it's usually good - without caring about the
why.
