Why is update not an option?

istep shipment put correct

Yes it is. Triple checked it

Could also be that for your ECUs, 18-03 is the highest i-Level and there have not been any software changes since then.

Okay. Then all f10s should not be able to be updated higher. Sounds Strange

Try to put on the istep shipment 18-03-530 and do a tal calculation

But that would not be correct then, when the shipment is 10-06-512. What will happen then? But I can try for sure
