How can I set the tariff unit rate in Energy IQ

I attempted to set this today and was unable to do so. I changed the unit to £/kWh and given my rate is 6.25 pence per kWh i tried to enter 0.0625 but the app would not accept this, turning the field red and disabling the "Save" button. In fact it would not accept anything but whole numbers which equated to Pounds per unit. Is this a bug or am I missing something obvious?

Thanks.
