Niagara Particle Sprite Rotation - Sprites are not facing the same direction?

I create a niagara emitter with a custom sprite of a cherry blossom petal. I want them to face all the same direction, and set the Initialize Particle with “Direct angle” of 90 degrees. However, some of the particles are “flipped” in the opposite direction. Any help would be much appreciated, thank you!

Solved it, had to set the Sprite UV Mode to Random X only or Random Y only!
