HomeAssistant-OctopusEnergy: Prices don't include government cap?

Describe the bug

I’ve just switched to Octopus last week, and as a result am on “Flexible Octopus” (for now) which contractually showed as 52p per kWh, but due to the government cap is actually 34.23p per kWh. The Octopus app and website both show as 34.23p per kWh, but obviously the API does not, as this HA integration is showing 0.52074225 GBP/kWh

To Reproduce

Have a government capped tariff. Sorry! I assume this is unlikely to be an issue with the integration and an API issue instead, but I thought I’d check and/or wasn’t sure if you had a contact at Octopus rather than attempting to explain this to the standard customer support.

Expected behavior

The correct price is returned.
