This has been mentioned before: AceDB does NOT write updated values to your saved variables file unless the user changes a setting from the default to something else.

If nothing has been changed from the defaults table, then nothing is written.

Let's say you have this default table:

local defaults = {
    profile = {
        pet = "dog",
        breed = "Doberman"
    }
}

When you load the addon, then exit out of the game, you will NOT see entries for pet or breed. Now load the addon again, and change pet to "cat"; NOW AceDB will write an entry that says pet = "cat".
