+      It occurs because of the place of each signal triggered in the OR condition : the order of the trigger in the condition matter.
+      If the triggered one is after the one who is already set as true, it will not trigger the alert because, for the condition value didn't change.
+      Else if the triggered one is before the one who is already set as true, it will trigger the alert.
+      We must separate the condition into three effect, a condition for each effect.
