Plants are invulnerable!

I have tried using modifyworld.blocks.destroy and modifyworld.blocks.interact nodes with PEX but they both don't work, grass is invulnerable unless you use a water bucket or break the block under it. I have tried item codes minecraft:tallgrass, 32:1, 32/1 etc... but no item codes work, grass stubbornly refuses to become uninvulnerable. I am using the version released by games647 here: https://github.com/games647/Modifyworld/releases
It may be because there is a newer version i'm unaware of if so please let me know the config.yml of that release has a bunch of unusable nonsense inside it (the messages never show up in game no matter what i do)
