Niagara Parameter Collection not getting set to the assigned ChunkID in pak file (always assigned to pakchunk0)

I am trying to create pak files, which I don’t have a problem with in general. But for some reason, only niagara parameter collections (NPC) are not correctly assigned to the Chunk ID I specify. It’s always getting assigned to pakchunk0 no matter how I set things up. If that NPC is assigned to a material collection parameter (MPC), which will be, then that MPC will be forced to pakchunk0 too, even if it was assigned to any other ID.

If anyone knows about this, please shed some light on this. Thanks in advanced!
