How to make spawned decals visible in both splitscreens?

I’m having trouble showing the decals spawned from an emitter with a collision event. The decals only appear for one player at a time.
In the pictures you can see an example from the game when it’s running and the character’s blueprint with the decal spawner.

If I disable splitscreen in the project settings, I am able to see the blood decals rendered on player 0’s screen (the left screen in the picture). However, when splitscreen is enabled and I have two players, it only appears on the screen of player 1 (the right screen in the picture). It seems the decals are visible to both players individually, just not at the same time during splitscreen.
