You seem to be suggesting that all cartridges, for all alignment geometries, should have their screws in the centre of the fixing slots?
If that were so, why have the slots?
You'll find different cartridges and different geometries will be accommodated by the screws 'moving' within the slotted holes.
Please don't lose a moment's sleep over this.
