...tested and one slot for Unified, no extra slots used. (no failing Ice refinery)
... tested and got one slot for unified + one slot for agregate, top on my list is Black ice refinery, what fails because have no ice, failed slot is moved next profession.

I hope that this is explains your issue, but lets look and investigate it tomorrow more , cheers, ;).
Bug with alchemy and version 1.10.06.01
if you put 1 slot in alchemy and customize the task list to create unified elements: it will not detect the ongoing task with unified element and start a 2nd slot making another unified element.
