Trying to Load Structure Template 1.14.4

So i'm trying to get a structure to spawn in my mod using an NBT structure i created but its not actually spawning. So i was able to register the structure and i'm pretty confident its in there in code but for some reason i cant use a structure block to spawn it. What would i need to do to get this working. Here is my git with the files and the NBT files from my GIT Any idea's on where i can go or what i can try would be helpful! https://github.com/drizzs/GrassWorld-1.14/blob/1.14.4-rewrite/src/main/java/com/drizzs/grassworld/features/GrassIslandPiece.java

https://github.com/drizzs/GrassWorld-1.14/tree/1.14.4-rewrite/src/main/resources/data/grassworld/structures

only the dirtisland variant is being used.

i'm assuming its not loading my template possibly
