[BUG] "state_of_charge_unit_white_space: false" completely ignored

[mkanet]

Version: v0.1.8.1

Describe the bug I am trying to remove the whitespace between the state of charge value and state of charge unit for Battery. Unfortunately, it is ignored. I am not sure how else to do it

To Reproduce

  battery:
    entity: sensor.mka_net_battery_power
    display_zero_tolerance: '10'
    state_of_charge: sensor.mka_net_charge
    state_of_charge_unit: '%'
    state_of_charge_unit_white_space: false  #This line is ignored!
    display_state: one_way
    color_state_of_charge_value: true
    color_icon: true
    color_circle: true

Below is my full card code, just in case something else in my code is interfering with the state_of_charge_unit_white_space setting.
