Sorting layer issue with multiple sprites and a Tilemap in Unity

Question

I have a particle system that draws a blood splat. I have a Tilemap that represents terrain. However, the blood splats, which are on a sorting layer in front of the terrain, are somehow rendered both in front of and behind the terrain.

I have encountered similar problems before where the particles had some different Z value than the terrain, but that is not the case this time (3D view):

Here are the Inspector panels for these objects.

First terrain:

The renderer for the upper (in Y) blood particle system:

And for the lower (in Y) system:

And finally my sorting layers, where Base is behind Foreground:

What might cause this behavior and how can I fix it?

Edit: Here is the entire BloodSplat prefab:

Well I got a few tips for you to try to get it working :

1. I'm not really sure what the exact issue is. I think it might might actually be a bug in Unity. Anyways, it deals with the SpriteRenderer and the order in which it is applied to the gameobject (relative to the Particle System).Try to remove the SpriteRenderer, and then add it (or just create a whole new gameobject and add the Particle System first). After doing this, You Should be able to change the sorting layer of the particle system. Another workaround would be to create a separate particle system gameobject and attach it (as a child) to the main gameobject.

2. Alternatively, you can specify when your particle system has to be rendered. You can check the particle systems rendering order in frame debugger and if you want to push it front, you can increase renderqueue value by increasing the Custom Render Queue value.
