Standing Charge not updated on Smart Tariff page

My Octopus Go tariff has recently changed. the peak rate has increased to 41p and the Standing Charge to about the same. However while the rate has been reflected in the dashboard and app card, the standing charge still states the of rate of 25p. Any ideas why?
I've removed and reloaded the API details but that hasn't helped. When I look on the Octopus Watch app which also uses the API, that reflects the correct rate so I'm not sure why this is happening. Hopefully someone here might.

Mine is showing a standing charge of 0p for Intelligent Octopus, would be great if accurate, but pretty sure I’ll end up being charged 51p per day.
