Block break coloring

Bliss Shader causing block breaking animation to change to a white color rather than reflect the block's color as is usually the case. How can I fix this? I'm using the most up to date version of iris and DH that I can find on this server (although the game is informing me of a new version whenever I launch the game. Don't know where I'd find any such update). It's a small problem but noticable.
