Smart Tariff Automation fault

Over the last week or so, the smart tariff automation has stopped sending stop charge times, instead sending start charge times when its due to stop. I've re-input the tariff times, restarted the router, inverter and battery, but the error persists. All other timings sent via the portal and app are received fine, it just seems to be the automation that wont send a stop time.
Any others with similar, or suggestions how to fix?
Think I've got a gen2 3.6 inverter on the most recent updates.

Had the same issue last night, I have just turned the automation off, not sure why it was on as I have a fixed cheap period from 00:00 to 06:00.

I've found a fix, but its not a very "smart" automation. So long as I leave the end charge time as 0600 the charge will start as per the tariff, so any other inputs in the day are overwritten.
Looks like its time for home assistant
