Google Home Speaker Log Warning

Any Ideas, I am getting this for all Google Home speakers (Except the Google Home Minis).

dev:2362019-11-12 02:14:57.965 pm warnnot parsed:{"requestId":0,"status":{"devices":[{"capabilities":229381,"deviceId":"49e0f96c-d6e4-c777-6fb3-549ef561bf20","name":"Office Display","volume":{"level":0.699999988079071,"muted":false}}],"isMultichannel":false},"responseType":"MULTIZONE_STATUS"}

I noticed they were "Chromecast Video" and when I changed them to "Chromecast Audio" the warnings stopped, would this be a bug in the Chromecast Integration (beta) App?

Thanks Matt
