Why can't I get bonus rewards from the Invocation of The Witches' Secrets?

In the Invocation of The Witches’ Secrets, there are 2 different types of benefits you can obtain.

1. Bonus Rewards
   
   • On the lower-right corner of the Invocation of The Witches’ Secrets’ screen, you can find the bonus rewards gauge. You will see the total pull count for this Invocation displayed as “(number)/(number)” inside it, as well as an item (the bonus rewards) above it on the right side.
   • After each specified pull count, bonus rewards can be claimed in addition to the items you have pulled from the Invocation.
   • However, when the bonus rewards for every specified pull count have been claimed, the total pull count will be stopped for the rest of the week.
     
     • The total pull count will be reset every Monday, 4:00 (Server Time).
     • On the lower-left corner of the screen, you can see the amount of time left before the reset
2. 10 Magic Crystals are guaranteed every 10 pulls in the Invocation of the Witches’ Secrets
   
   • Under the bonus rewards gauge, you will see a box with the message, “(Number) pull(s) to get 10 Magic Crystals.”
   • On every 10th pull, you are guaranteed to obtain “10 Magic Crystals.”
   • The total pull count mentioned above only affects the bonus rewards of this Invocation, so you will always get 10 Magic Crystals on every 10th pull.
