Each figure has its own barcode, and the way coles group works is head office inputs the barcodes into the system.
Often they only enter 1 out of the box of (say for example) 4 and gotta wait for a complaint to come back from store.
It's not fixable at store level, so don't try complaining about it there.
To group them all together, and reorder, they often make a general code to group all the different barcodes under. Seeming these are the last delivery, someone must have skipped a step somewhere and they fell through the cracks.
