Sorry I’m confused; what is the thing drawn at the origin and what makes you think they are parented? If you lower the ground, and maybe rotate it a little, do they not fall independently? They have a slight separation at the start, likely because their geometry overlaps.
I noticed this is version 2023.10.05, there were a number of patches released after this, up till 2023.10.11, could you give that a try?
See the changes in the comments above that one.
