Raw ores will not smelt

I am playing in survival world, no cheats, no mods, no dlc. I mined iron and got raw iron and attempted to smelt it in a regular furnace as well as a blast furnace. It did not work. I also attempted to smelt raw copper and it didn't work. I tried multiple furnaces as well as multiple types of fuel. Nothing is working and it makes the game unplayable in survival mode. Please help resolve this issue. Thank you.
