Solution
The reason why the other loops stop and the one with the event structure doesn't is because the value change is passed to all the local variables but the loop with the event structure keeps running because there is no event triggering the loop to run. Once the event has been triggered, the Boolean value will pass to the terminal condition and stop that loop.
To solve this, you can add an event for the stop button when its value changes. This means that when you press the stop button it will enter the event and then the value will pass to the terminal condition, stopping this loop and the others that are linked by the local variable.
The following snippet show two parallel loops, one with an event structure and one with a local variable wired to the terminal condition. This shows how to set the stop conditions so both loops stop when you stop the one with the event structure.
