Each row is one kind of setting. Saved means the database answers; from file means a yml on the server still does.

Show current value looks up what this business or outlet actually gets right now.
Save stores the editor contents as the whole value, replacing anything there.
Save changed keys only merges your keys into the stored value and leaves the rest alone.
Remove override deletes the stored value, so the setting falls back to the level above it (or the file).

Click any row to open it. This is the list of saved overrides — it does not show settings still coming from a file. A row existing does not always mean it is the value in use: a more specific outlet row can win over a business one.
