How to let Cubase always read automation?

a midi track is not always reading automation, unless there’s a change, a dot. How can we let it always read the automation?

I met this question with control 3 instruments on one midi track that, when I’m on first instrument, volume is set to 0, then I switch 2nd instrument, volume goes to 100, then switch back to frist instrument, volume keeps at 100, but cubase is not reading it, the 1st instrument’s vol is still 0, I’ll have to add a dot , make some small changes then cubase will get it and the 1st instrument’s vol will be right.

I’m on cubase 7.5
