Object: Visibility will only work for GameObjects that have a Renderer component attached.
What kind of text object? Unity UI or GUIText? If it's Unity UI, you could try linking it to an AC Menu so that you can control it with the Menu: Change state Action.
You could also attach an Animator to your object, and create a "Hide" animation that you play using Object: Animate when you want it hidden.
