Icinga Web 2 is still showing "Check Timeperiod" after check_period was removed from the service

  • A bit of (unrelated) background...

    I was trying to force check to be executed once in the morning giving it a 60m window via check_period with check_interval of 45 minutes.

    It didn't work. :|

    Anyway...

    I decided to remove any check_period restrictions and just set check_interval to 12 hours.

    After removing check_period, reloading configs, refreshing web browser window (even logging out and logging back in) Icinga Web 2 is still showing name of check_period I had for the service before.

    I did check the service object via icinga2 object list command.

    And check_period is empty string.

    Is there anything I should clean / flush / refresh?
