Artifacts when spawning particles in Niagara

Hello! I’ve made a liquid flipbook but when I use it in Niagara and spawn more than 1 particle it gives me these weird artifacts. I mostly use the translucent shading model when doing particle work so I don’t usually encounter this type of bug but for this I went with the opaque masked shader. Any Ideas?

here is a link to the video that shows my issue : Particle artifacts
