EnderCrystal Beam Incorrrect Direction

I use this command to make endercrystal shoot beam to a target with this command :

/summon EnderCrystal ~ ~1 ~ {BeamTarget:{X:33,Y:19,Z:9}}

The dragon head is at that position

But It was reverse texture

This happen at the first version that have endcrystal item
