The amount of iron ingots is not correct when creating them from an iron block

I had 27 blocks of iron and when I went to turn them into iron ingots, the number that appeared on the iron ingots symbol was the same as the iron blocks. Shouldn't it be 99+ iron ingots? Each block of iron is made with 9 iron ingots. So 27x9 is more than 99 (is 243). I'm not sure if this is a bug or something.
