When activating the "Only show prepared spells" option, only certain cantrips will show for spell casters. An example, a druid in my group has only Resistance showing as a cantrip in his spells, though he has Control Flames, Create Bonfire, and Mending chosen as cantrips. A cleric in my game has none of their cantrips available, and a High Elf ranger does not show his racial cantrip as an available option.
