2 car charging issue

[mask2082]

I might be missing something, but here is my problem. I have been using batpred for a while and have solar, battery, iboost and ohme ev charger. Everything works as expected and up until now I was charging 1 car without any issues. Today I have tried to set up a 2 car charging. In apps.yaml I have set:

num_cars: 2

car_charging_planned:
- input_text.ohme_home_pro_status_merc
- input_text.ohme_home_pro_status_jaecoo

car_charging_planned_response:
- 'plugged_in'
- 'charging'

car_charging_exclusive:
- true
- true

car_charging_battery_size:
- 105
- 18.3

car_charging_limit:
- sensor.XXX_max_state_of_charge (numberplates removed)
- 100 (don't have a sensor for this car yet)

car_charging_soc:
- sensor.XXX_state_of_charge (numberplates removed)
- 0 (don't have a sensor for this car yet)

and also the Octopus slot information:

octopus_intelligent_slot: 'ohme.list_charge_slots'
octopus_intelligent_slot_action_config: 'MYCODE' (removed the code but it is setup)
octopus_ready_time: 'time.ohme_home_pro_target_time'
octopus_charge_limit: 'number.ohme_home_pro_target_percentage'
octopus_slot_low_rate: false

The car_charging_planned: responses are coming from an automation that sets the value to plugged_in or charging for the car that is plugged in and unplugged for the second car. That bit works and values are being set correctly. But batpred only plans the car charging if it is the first car that has the value plugged_in in the car_charging_planned:. If I swap them round and "make" the second car as plugged _in with the first one unplugged then the plan does not show anything in Car kWh column. If the car is charging then in the second line car scenario power gets drawn from the battery, naturally, as there is no car charging planned.

Where am I going wrong? Please do let me know if you want me to share any files.
