Closing as not a bug. You are missing an "Else" condition in event 3. As it stands, event 4 (else, meaning "slider value is not < 2") will always run when the slider value is >= 2, overriding the "Slider value > 5" event. You probably intended to have an else-if chain, as in:
Slider value > 5
-> "greater than 5"
Else [ <-- this was missing in your .capx]
Slider value < 2
-> "less than 2"
Else
-> "in between"
This works correctly.
