Hey @ANGI hmm it looks correct to me, I just did a test on an account as well to double check:
1st is before, 2nd is Mydnight Kingdom level 10, 3rd is Mydnight Kingdom Level 15:
This data is pulled from your account progress iirc, so there shouldn’t be an issue with this number even if there was a connection problem or other issue preventing the Team bonuses to update at the time of the Kingdom Level up as it would just correct next time you refreshed.
If you submit a support request we can have a closer look at your account data if you’d like but it does seem to be what is expected from the cursory checks I made and there doesn’t appear to be an overall game bug.
