Please keep in mind that a sign should not be placed twice in one Biome, as the Quest step may not register as complete this way. Also, if you move one of the Oogie Boogie signs from one Biome to another, it won't count towards the Quest step anymore. You will need to remove it and replace it.
I have put all 8 Oogie Boogie signs in each Biome for the "Dreamlight Day" Quest, but it's still showing me 7/8.
