2 automations points in the same time period?

I’m having a little trouble making a perfectly straight line in a cutoff automation I need to be really exact, it only lets me go back so much to the line I´m looking to alter, instead of the cutoff looking like ‘’ | ‘’ it looks more like a slight bend lin ‘’ \ ‘’ any idea or workaround, guys?

Thanks

Either disable ‘snap to grid’ in the horizontal axis (the popup menu next to the magnet icon), or set interpolation to ‘point’ instead of ‘linear’.
