Custom Grass Not Blending With Dirt

[Spoon G.o.d]

I have seen very few people talk about this, so I thought I'd ask. I can't for the life of me get the grass texture to blend with dirt, it doesn't blend when it spreads or when it generates in the world. The grass does blend correctly with itself however on any other blocks it does not. I know that grass has a different tile set layout than other blocks but maybe that's changed since I last was modding. ANYTHING HELPS

I have the main three block blending functions enabled:
Main.tileSolid[Type] = true;
Main.tileMergeDirt[Type] = true;
Main.tileBlockLight[Type] = true;

Attachments are the tile set, world view, and map to show that there are "invisible blocks"

Check ExampleSand here as it's an example block that blends into dirt, and make sure your sprite lines up also:
Tiles

This does not seem to fix the issue unfortunately
