Cannot show status bandwitdh hourly, daily, and monthly

I have two balance 710, and configuration with HA. But if i check status bandwitdh for hourly, daily, and monthly its blank. It happens in master or slave. If i check status realtime its ok, I can see the use of bandwitdh. What problem it is?

Thank You
