It’s impossible to be sure, but I suspect that the meter’s tariff data either hasn’t yet been updated or needs updating again. Please check your Plan page; that’s where you’ll see the rates that apply to your account, the ones that will be used to calculate your bill. The rates you see on the meter are supposed to be accurate, but they’re only for your information. It might take a few days for this to come right.
If the rates shown on the Plan page are also different from the ones you expected, Support should be able to put it right. They can also ask for the meter to be updated with the correct tariff data.
