If I use a command generator to create a chest with items in it and then put it down there are no items in it. In vanilla minecraft if I use the same command and then put it down there is nothing wrong.

This is the command that I am using: give @p minecraft:chest{BlockEntityTag:{Items:[

{Slot:0b,id:"minecraft:dirt",Count:1b}

]}} 1

This works well in creative but not in survival while it works in vanilla minecraft.
