Can not craft polished deepstone

When I try crafting deepslate it says there is none in my inventory.I was crafting polished deepslate until it said I had three and not the multiple stacks I had .When I got the deepslate out of my inventory then back in it said I have none.This is not just in the one world either.All of the existing worlds I have I can not craft polished deepslate. I had a copy of the world and I seem to be able to craft it on that world.Any other existing worlds I have I can't.
