Dashboard blocks crash my Simulink by using all of my PC's memory(MATLAB 2016b)

When I try to use the Lamp block of dashboard , I have to connect the signal with the Lamp block, then the signal will have an icon on its line as shown below, and then I start the simulink(Stop time set to "inf"). I find that my memory use is continuously increasing(eventually go up to 100%, total memory is 16GB), then Simulink won't update the state of Lamp. For example, when the memory reach to 100%, the color of Lamp won't change anymore even though I change the signal it has connected, and Simulink will become really slow. After some experiments, I find the problem is "Stream Selected Signals"(By right-clicking the signal line). As long as I stop the "Stream Selected Signals", the memory won't rise up again, but the PROBLEM is if I want to use the Lamp block, I must start the "Stream Selected Signals", What should I do?

What's interesting is that this problem will appear in R2016b, it won't happen in R2019b. I have tested the same model in R2019b, the memory problem won't happen, and I can't find the "Stream Selected Signals" icon in the signal line in R2019b. Is this problem can solve in R2016b?
