Random Pal Chest Problem in Daily Rewards

I didn’t collet Pal chest today but tick mark on the pal chest when I saw daily reward page . Todays chest contains random pal. But I didn’t reward any pal.

I’m playing on Windows 10. I didn’t use facebook. And only collect free pal chest before 24 PM. Now 1 AM here. 

the same problem can happen too in inverse. You can have it on your calendriar no tick mark and you have received it anyway same if that was not this one. After the calendriar is totally change and don’t match anymore on your previous calendriar

like each year during holiday this bug happen so no surprise this year :

This is the calendriar before the bug :


After the bug :
