Changing Value of Utility Meter Tariff sensor

so I have a utility meter that has three tariffs. one of the tariffs is showing a large jump so I want to just go to developer tools and states and set it back to the previous value. when I do this it changes the state but during the very next reading it jumps back to this massively large number. when I look at the state of the device, it is a filter and all the values show correctly and it has no large spikes in any of the readings. but the utility meter keeps showing a large spike the next update every time I reset it.

Should I not be able to change the value of a utility meter tariff sensor? is there a value stored somewhere else that contains this wrong read? if the state of the filter is correct and the sensor for the utility meter has been set back to a proper value… why does it keep reverting back to its old value??

This is in regards to this post

just trying to break out my troubleshooting steps…
