Fortune doesn't work on the latest Beta

My Fortune pickaxes doesn't work on Survival... I tried Fortune II Diamond Pickaxe to 5 Diamond ores, I only got 1 out of each individual ore... I mined a number of Coal and Redstone ore with my Fortune III Diamond Pickaxe but again I only got 1 coal and the usual drops of redstone to equal to number of a normal pickaxe would drop
