I don't knoe what's changed! The "kill the mic rumble" preset was working just fine untill a few weeks ago!
Now it does nothing! It will not change anything!
Can you show us a screen grab of what it looks like now?
Of what, what look like? There is no prompt or anything, the preset just does not do anything, anymore!
If you open the effect, select the preset, what does the screen show? Does it look like this?
