Decals disappearing simultaneously

Hello everyone.

I’ve had this problem with decals I couldn’t work my way around, or even find any info about it on the interwebs or forums.

After spawning several decals with the “Spawn Decal at Location” function, with a Life Span of 0 or over 30, they all disappear simultaneously after a period of time, despite the amount of them present on scene.
However, should I pick a shorter Life Span, of 5 for example, they correctly persist individually for those 5 seconds.

Could it be some setting I haven’t bumped into, some hard coded thing or even a bug?
