Using /blockdata or /setblock to change beacon effects to any potion effect not given by a beacon by normal means no longer works.

*Added note when using the commands of /setblock and /blockdata I had 4 layers of valid blocks for the beacon to have it give full lvl4 beacon effect range or 9x9 Emerald Block base with 7x7 Diamond layer above that 5x5 Gold block above that 3x3 Iron block above that.
*the block being targeted by the tag: "replace" was a block of iron

*Exact commands used:

/blockdata ~ ~-1 ~ {}
/blockdata ~ ~-1 ~ {Primary:x,Secondary:x}
/setblock ~ ~-1 ~ minecraft:beacon 0 replace {Primary:x,Secondary:x}

x= "2, 4, 6, 7, 9, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27" When these values are used and then after using "/blockdata ~ ~-1 ~ {}" the game states the values for tags: "Primary, Secondary" are set to "0"
x= "1,3,5,8,10,11" the commands work as should.
