When clicking an item in the crafting table shown in the image, you are unable to see what items are needed to make said item such as the new soul campfire or black stone walls and for new players this would be a problem, as well as all of the items going into the crafting table so if you have a specific way your items are in your inventory, they will be placed else where in your inventory

It might not be a bug but it is confusing why this has happened.
