EQ Automation bug? EQ Automation "leaking"

Hi

This happens with the built in channel EQ as well as Cubases Studio EQ.

Lets say I’m doing a low pass filter sweep upwards effect on a Kick 4/4, the first beat cuts through the filter as if it’s not activated/automated then after 1 beat the fitler/automation suddenly kicks in and 'activates" and does it’s job and low passes everything.

The setup is a Studio EQ automation on 1 Stereo output of Groove Agent SE

Linked is an example happens at bang on 4:00
