Help with configured feature for ore generation

My datapack validation is failing. I get this in the output log: > Failed to validate datapack > java.util.concurrent.CompletionException: java.lang.IllegalStateException: Unbound values in registry ResourceKey[minecraft:root / minecraft:worldgen/placed_feature]: [aaoo:glacio_osmium_ore, aaoo:mars_osmium_ore, aaoo:mercury_osmium_ore, aaoo:moon_osmium_ore, aaoo:venus_osmium_ore] > at java.base/java.util.concurrent.CompletableFuture.encodeThrowable(CompletableFuture.java:332) > ... I think it is potentially because I tried to make subfolders inside of my configured feature and placed feature folders, since they were getting quite large. Is there a way to do this, or do I have to leave everything in the main folder?
