How do I keep the current automation value when writing?

I’m trying to record an automation curve to the track. I noticed that it only writes to the curve when I move the controller knob. As soon as I stop move, it jump back to the default value and stop writing the automation curve.

How can I tell Nuendo to keep writing the automation curve with the last knob value, instead of jump back to default?

Change the automation mode from touch to auto-latch.
