Describe the bug
After upgrading HA from 0.107.x to 0.109.2 show_units does not work anymore.

• When set to false it does show original unit regardless of presence or value of 'units' attribute.
• When set to true 'units' attribute is shown (correct) or original unit when attribute not specified

Version of the card
Version: 3.3.2

To Reproduce
This is the configuration I used:

          - type: "custom:button-card"
            entity:  sensor.owm_pressure
            template: bedtoom_entity_card
            icon: mdi:gauge
            name: Tlak hPa
            styles:
              card:
                - height: 165px

#### definition of template elsewhere ###

  show_state: true
  show_units: false
  styles:
    grid:
      - grid-template-areas: '"i n" "s s"'
