That's strange for sure. At the same time, it would be more clear if you also upload the screenshot of your previous week total lottery ticket number. Because you had received $47 from the previous weekly bonus. $47 is a quite high amount as the weekly bonus for a new silver ranked user (if you haven't lost big). Maybe they had given you higher bonus in the previous week and adjusted it in this week.
Yup strange, it's a bit difficult to explain this case he should have qualified for the last weekly bonus. If it was a miscalculation, he shouldn't be the only one to experience it I think he's obscuring something whether it was intentional or not. I've heard stories with similar cases, a user shared in a group about low bonuses but no one can respond with proper reasons but later he realized that he claimed the bonus with a different account, I'm sure you understand what I mean

To make sure this case we have to wait for the weekly bonus of this period who knows the wager will be calculated this week.
Please note that the weekly bonus calculation differs by 1+ hours from the ticket calculation, means wager after weekly out still counts for the Weekly Raffle/tickets in the same period so tickets cannot be fully used as a reference for the weekly bonus because there is a difference of 1+ hours from the calculation.
