Wrong cost in app in emoncms

On the emoncms both local and online when using the app/MyElectric the cost total for the day seems wrong. For example the current use for today so far is 5.5kWh. But toggling to cost it shows £5.5 and I definitely dont pay £1 for a kWh (yet!). The power now and toggle cost on left hand side seems correct though. I have the unit cost in MyElectric config set correct as far as I know. Is this a bug or have I got something set wrong.
