Guide default to Favourites

Hello,
I have been using Channels on my AppleTV for many years now. I have it set to default to guide and from there it defaults to Favourites. Since these are the channels we always watch.

However sometime over the past couple of weeks something changed so it doesn't default to Favourites but to 'All Channels'.

Can anyone advise on how to get it to default to Favourites again?

It's causing me to come into the room and find SD channels on!

This is a bug and was already resolved and is available in the latest testflight beta release.
