How can I fix the particle system from not displaying correctly in VR?,How can I fix this?

Hi I have created this particle system to simulate rain in VR. It looks fine when simulated in the editor but as soon as I run it in VR it looks really strange, like the objects in the scene (particle system included) leave a train behind (see attached screenshot). If I remove the particle system from the scene everything looks OK in VR so the issue must have something to do with it.

I have no idea why this is happening or how to fix it. I am using Unity 2020.3.

Can someone please please help me? :))
