Same here. Since I usually anyway have checked luggage I simply stopped to do OLCI if APIS is needed.
Also when flying to/from US SK liked to annoy me with this at OLCI even when I have entered all required information before. And I absolutely don't get why I need to enter the information also for the return flight again. I don't change my passport like underware.
