Dripstone cave command /locatebiome not working, dripstone caves no where to be found within world

When I load in a world and go into spectator mode, I cannot find any dripstone caves. When I do /locatebiome minecraft:dripstone_caves, I get the same error message that there are none in the nearby error. So I move thousands of blocks away and get the same error. The screenshots provided are from three separate worlds.
