Changing sprite of ParticleSystem doesn't work?

I am working on customizations and I want that my players sprite is the same as the sprite of his hurt particle system. The code based stuff works that proves the picture because the players sprite is a diamond and the diamond is assigned. However as a result I get squares… Can anyone help me please out I’m stuck because I havn’t found any solution for it.

Turns out that it’s because the sprites are made from unity directly. But it works with other sprites you designed yourself . If you have the same problem just don’t use the sprites you can create with Unity.
