Weekly Goals bug (won't let me redeem)

So I did 6 out of 6 weekly goals but for some reason it only assumed I did 5 out of 6.

Because of this, I'm unable to redeem my Tix and Rip chips.

I wouldn't really care if it were daily challenges because I can just do another ones the next day but it's weekly challenges and a reasonable amount of currency.

I'm not sure what happened or what am I supposed to do to be able to fix this.
