Val's Diner not calculating properly on playing

Val's Diner is not adding points earned after completing a challenge. It adds the 30 points but then after you give up it goes back to previous count and does not increase the 30 points earned . Not understanding why it also only gives 13 points when you earn 30 points. Can someone assist on how this can be corrected so I can complete the Event challenge, This is taking forever and have used up many boosts to win and my points are now down and needs to add correctly so I can redeem again later. Please tell me what is wrong as this has been going on now for two days when I complete the eight games allotted. Thanks.
