Cannot load sensors after upgrade

[Ov3r0n]

I recently upgraded powercalc to the latest version and I'm getting this error everytime HA starts:

Traceback (most recent call last):
  File "/usr/src/homeassistant/homeassistant/setup.py", line 235, in _async_setup_component
    result = await task
  File "/config/custom_components/powercalc/__init__.py", line 166, in async_setup
    await autodiscover_entities(config, domain_config, hass)
  File "/config/custom_components/powercalc/__init__.py", line 205, in autodiscover_entities
    manual_configuration = get_manual_configuration(config, entity_entry.entity_id)
  File "/config/custom_components/powercalc/__init__.py", line 245, in get_manual_configuration
    for item in sensor_config:
TypeError: 'NoneType' object is not iterable

My sensors are configured like this:

I've tried disabling and re-enabling some of the sensors with no luck. Any help will be much appreciated (BTW great work with the component, love it!!)

Should be fixed in v0.22.1

Should be fixed in v0.22.1

Verified. Works as expected.
