Display closing date on closed events

I see the “Will the price of ether be above $10 on 3/31” event is now closed. I thought it was supposed to close later than now, but I don’t see how to check this.

It appears in the closed market for me as well. I have some shares but the market is now closed, not sure why it closed prematurely. This happened on the will the network society build an asset on ethereum market as well.
