Blast Furnace and Furnace doesn't cook Iron equipment

When I try to cook Iron equipment in a furnace and blast Furnace it doesn't start to cook. Then I've tried in another location in my world and it works until I remove the first 64 iron nuggets, then it stops working. This is a bug because a can cook normally golden swords and it happened the same to another player.

I'm sorry, I have reported this before but in the wrong project and I can't edit the project type or delete the post
