Error with lighting

Have blocs and hyphenated in the form of drop, and also in inventory there is mistake with lighting. the drop does not accept the level of light around him, and becomes darker, and Vice versa, is highlighted.

What I expected to happen was...:
Blocks and objects in the form of drop become darker or lighter depending on the level of lighting.

What actually happened was...:
blocks and items in the form of drops, and wearing of weapons are easily detected in the dark and always light.

Steps to Reproduce:
1. Play Minecraft
