I experience the same problem bro. The costumer service told me to clear cache and try again. * I'll report my inquiry and content of my post here.

Hi guys can u still redeem the items/ rewards in Faithful Choice? The event in our server will end at 14:59:59 of JULY 30 2017

On the picture, it is only 2:02:25 of July 30 2017 but I can't redeem items from the redeem shop of Faithful Choice event. I have 960pcs kunai and I want to redeem 9 pcs Charm Pack and 2 pcs Advance Refine to consume my 960 pts but it wouldn't let me. It said not on the event time.When I checked the rules of the event, It is said in the event on the last day you cant participate in the battlefield and consume the orb of vitality but can still redeem the rewards right? Why I cannot Redeem and use my 960 points today?
