Removing references to BOM Integration

With the recent removal of the BOM integration, I have moved over to using the bureau_of_meteorology sensor platform by bremor and it seems to be working. I have removed references to the bom sensor platform in my configuration.yaml and removed bom_forecast (via HACS) but I am still getting configuration errors:

Platform error sensor.bom - Integration 'bom' not found.
Platform error sensor.bom_forecast - Integration 'bom_forecast' not found.

Is there something else I need to do to remove them? Or is there some way to pinpoint where they are being referenced?

I removed mine ages ago so have forgotten how I achieved it, but have you looked to see if it appears on the Configuration | Integrations page and if so remove from there?
