Help with custom templates

Hi, I seem to be having issues with UI cards and custom templates.

For decluttering, I am adding the templates in lovelace\decluttering_templates

For Lovelace Minimalist, I am adding the templates in ui_lovelace_minimalst\custom_cards.

What am I missing here?

Thanks

Can someone please help explain how this works.

I have no found that the templates are stored in /homeassistant/custom_components/ui_lovelace_minimalist/ui_minimalist/ulm_templates/community_cards/custom_card_person_info/custom_card_person_info.yaml

But now I am getting this error.

I have spent a whole day trying to get this to work. Do I need to edit the attributes in the template file directly, as I tried but it reverts back to default on every reboot.

Code from the template.

  variables:
    ulm_card_person_use_entity_picture: false
    ulm_card_person_zone1: ""
    ulm_card_person_zone2: ""
    ulm_address: ""
    ulm_address_locality: ""
    ulm_card_person_driving_entity: ""
    ulm_card_person_battery_entity: ""
    ulm_card_person_battery_state_entity: ""
    ulm_card_person_commute_entity: ""
    ulm_card_person_cummute_icon: "mdi:car"
    ulm_multiline: true

and code from the card.

- type: "custom:button-card"
  template: card_person_info
  variables:
    ulm_card_person_entity: person.lee
    ulm_card_person_use_entity_picture: true
    ulm_card_person_zone1: zone.uw
    ulm_card_person_zone2: zone.store
    ulm_multiline: true
    ulm_card_person_driving_entity: binary_sensor.lee_in_car
    ulm_card_person_commute_entity: sensor.uw_commute
    ulm_card_person_commute_icon: mdi:bus
    ulm_card_person_battery_entity: sensor.lees_phone_battery_level
    ulm_card_person_battery_state_entity: sensor.lees_phone_battery_state

Do I need to enter the values in both the card and the template?

Would really appreciate some help on this one.
