Utility Meter incrementing even when tariff inactive

Hi guys,

Having a weird issue with a recently-setup utility meter. I want to see monthly energy usage between 10am-2pm and 2pm-10am so I created a new meter with two tariffs, Peak and Off-Peak, that resets monthly. Despite having the very same formula as a daily-resetting meter that works perfectly, the monthly Peak meter continues to increase, between 10am-2pm, even when the Off-Peak tariff is selected:

The Off-Peak meter doesn't do the same - it isn't active between 2-10:

Both meters get the grid usage from a Frient device. This is the automation to deselect the monthly (and daily) Peak tariffs:

Does anyone have any ideas as to what's going on? Cheers!

i think a reboot fixed it.
