Creating a float variable named lifespan in an Actor Blueprint and setting a default value for it will override the parent class' life span setting. I was unable to find any variable in the Actor class named lifespan, but there is a variable named InitialLifeSpan that stores the default life span for the Actor.
Either the Blueprint should not allow a variable to be named lifespan, or that variable should not override the parent's life span value.
The Blueprint will print to the screen a countdown from 5.0 to 0.0, when the Blueprint will be deleted from the level.
The Blueprint will print to the screen a continuous series of 0.0 values and will not be deleted from the level after 5 seconds. Alternatively, the Blueprint will not allow a variable to be named lifespan.
