Energy meter collecting peak/unpeak simultaneously

Hello,

I am consufed as kWh are collected on both peak and offpeak meters during the night. The switch happening at 7 AM I should have only offpeak before 7AM and peak after 7AM. However I do have peak and offpeak in the night.

The meter select is set correctly to offpeak all night long as in the screenshot below. Any idea why this is happening ?
