Atlantis heros disappearing at summons screen

Name says it all. At the Atlantis summons screen, the featured heros will begin to disappear. Sometimes one, sometimes two or three. Anyone else see this? As the “normal” available heros scroll through the featured blackout. Does this mean anything? Is this a way of saying their is zero chance of getting those specific blacked-out heros?
