Express 24/48 tracking problems

My school theater is using an etc express 24/48 and I am having some programming problems.

I am trying to record cue 1 with channel 1, 2, 3 fade up in 10s. After 3s  followed by cue 2 with channel 4 fade up in 3s. At the same time, cue 1(channel 1, 2, 3) is still fading up since there are still 7 seconds left.

Here is how I record my cues,

Cue 1: channel 1+2+3@full  time 10  follow 3

Cue 2: channel 1+2+3+4@full time 3

The problem I am having is when cue 2 starts to progress, the level of cue 1’s content, channel 1, 2, 3, will suddenly rush to full intensity in 3s as well as channel.

I have tried to record cue 2 with pre-wait function but the result is still the same.

I know this can be solved with tracking mode, but I couldn’t find any tracking related setup in the system.

Is there any way to record the scene I want?
