I found this too.
My issue was that I have to set like 10 frames latency so the the content does not before the censoring applies.
But AFTER clicking to another page, you can still the the uncesored part because the new censoring is already applying to the new page, but the old page is 10 frames behind ...
So for all the filters, I changed `stay detected during` to the max. setting of 1 second. (I haven't tried setting it to less yet)
Works like a charm.
