LT8602 and LTspice

Hi all.

I'm simulating the LT8602 with LTspiceXVII.

The four outputs are: OUT1=5V, OUT2=3.3V, OUT3=1V and OUT4=1.8V

I'd like to have the follow startup sequence: OUT1 -> OUT3 -> OUT4 -> OUT2 

For OUT1, OUT3 and OUT4 there are not problems but I do not understand the OUT2 trace because it is about 0.5V before 2.4ms and after it goes immediately to 3.3V without the soft-start.

The green trace (V(n009)) is the voltage in the TRKSS2 input.

Where am I doing wrong?

Thank you.
