To anyone that can help me please 



I am applying for Australian citizenship online, and I am stuck on a question that seems be affected by some sort of a glitch because it doesn't make sense.
On page 3 of the application it asks,
Do you hold or have you ever held citizenship of any other country?
The answer is yes, I am a citizen of Canada and of Greece. But what I don't get is why it is asking my the date citizenship ended. What am I supposed to put for that? Neither my Canadian nor my Greek citizenship has ended, and it won't let me put N/A in that spot, I have to put an answer.
Does anyone have any idea?
TIA
