No status text on tile

I expected to see the word “Open” or “Closed” on this contact sensor (new app):

IMG_0614

Clicking the right arrow, shows detail page with what I expect:

The device handler:

metadata {
	definition (name: "Particle Garage Door Sensor", namespace: "b", author: "B", cstHandler: true) {
		capability "Contact Sensor"
	}

	simulator {}

	tiles {}
}

def handleStateUpdate(update) {
	sendEvent(name:"contact", value:"open")
}
