i am unsure what happened, but i cannot spawn loaders. And it deffinitely didnt spawn 2 and 2 ghosts.....
All i did was to copy past the blueprint above.

Edit:
Brand new station:

something is deffinitely bugged

Edit2:
Removing and adding (less and then more) wagons did the trick. Now its working. Somehow.

Mine won't spawn when there's a powerline above/crossing the railway. Go figure.

I noticed that when using LTN the button to place loaders will sometimes act on a different station (I think the last one that was interacted with).
I didn't test this extensively, nor I am sure that LTN is actually involved in the problem.
I worked around this problem by adding and removing a loader slot (with the + and - buttons in the GUI) every time before placing the loaders. This seems to set the station to the currently selected one.
