Hi,
I’m having a problem with labels in a config flow of a custom component I’m preparing. I looked at all relevant threads about strings.json, en.json, browser cache issues, etc. but I didn’t solve.
This is the config dialog box: the problem is with the 3rd field, which has a default value of 2, the field name is slave_id. The label/comment for that field does not appear. It’s not the browser cache, and if I update some labels in en.json the updates are actually being picked up. It’s like the “slave_id” field is not found in some way. The problem is only the label/comment, if I submit the values the component works fine.
This is the content of en.json under the translations subdir:
{
"config": {
"title": "ABB Power-One PVI SunSpec",
"step": {
"user": {
"title": "Inverter Connection Configuration",
"data": {
"name": "Assign name to the inverter (used as sensors' prefix)",
"host": "IP address of the inverter",
"port": "TCP port of the inverter",
"slave_id": "Modbus Slave ID of the inverter",
"scan_interval": "Polling period for the modbus registers (seconds)"
}
}
},
"error": {
"already_configured": "Device is already configured"
},
"abort": {
"already_configured": "Device is already configured"
}
}
}
This is the content of config_flow.py:

return True
return False
async def async_step_user(self, user_input=None):

errors = {}
if user_input is not None:
host = user_input[CONF_HOST]
if self._host_in_configuration_exists(host):
errors[CONF_HOST] = "already_configured"
elif not host_valid(user_input[CONF_HOST]):
errors[CONF_HOST] = "invalid host IP"
else:
await self.async_set_unique_id(user_input[CONF_HOST])
self._abort_if_unique_id_configured()
return self.async_create_entry(
title=user_input[CONF_NAME], data=user_input
)
return self.async_show_form(
step_id="user", data_schema=DATA_SCHEMA, errors=errors

Any help would be greatly appreciated, I want to release the component, but I have to fix this last issue first.
Thank you.
