1. Click on /home, confirm Device Type is set to Btrfs, then click on Modify. In the Configure Volume panel, change the volume name to something sensible like maybe f20home, check Encrypt, and Size Policy to Fixed. Then click Save. Then click Update Settings.

2. Click on /, confirm Device Type is set to Btrfs, then click first on the Volume pop-up and choose to create a new volume and give it a new name. Make sure Encrypt is unchecked. Set size to either Fixed with a particular value or As Large As Possible. Click Save. Click Update Settings.


That appears to work for me, at least it created the layout correctly and starts installing (I killed it at about 1% complete so I'm not absolutely certain it finishes but it should).
