1. Run the Cronometer Android phone app.
2. Make sure Diary Group is selected (Profile -> Diary Settings -> Show Groups in Diary).
3. Edit an existing food entry (tap entry, edit, Edit Serving).
4. On revisiting, the food entries are reordered randomly(?) within the diary group and did not preserve its position before it was edited.
Diary Group step is based on observation only. It may not have anything to do with the issue at all.
