Redstone Block texture not working when placed with a commandblock and command /setblock

What I expected to happen:
Redstone Block constant replaced by another Redstone Block

What happened:
Redstone Block immateriality replaced by a purple-black squared block

Steps to reproduce:
1. Put this command in a commandblock: /setblock ~ ~ ~-1 minecraft:redstone_block 1 0 replace
2. Place a Redstone Block at the negative Z side of the commandblock
3. You should get the 'no texture' block
