I have a bug where the Sync Options '
when syncing' reset to default when switching away from 'Auto populated from books on device'. The setting gets saved even when the window is cancelled.
1. List Type: 'Auto populated from books on device'
2. List Type: Manually or Search
3. Change the default 'when syncing this list' to another option 'e.g. Replaced device with list' (SYNCREPNEW)
4. Switch between lists and the setting will reset.
5. Return to 'Auto populated from books on device' and Cancel
Peaking at settings will be back to "listType": "SYNCNEW" so not a display bug.
