Assistant and hass.io apearing as source of my devices in Google Assistant setup

Hi, The other day I was going to add a new device from my Google home app and I found that I had 2 different sources from HomeAssistant for my HA integration: 1)Assistant, 2)hass.io, that seemed weird to me. I am connecting HA and Google assistant via NabuCasa. Why do I have hass.io devices on one hand and Assistant devices on the other hand?? I also had the names of my rooms (where you locate your devices) duplicated within Google Assistant setup . Why is happening all these?? Thank you!!.
