Easy way to track the changes for each document field
Create a document, enter some values and then press several times save without changing anything. Although you picked "Always" at the create audit configuration document there will only be one audit.
For an Audit to be created all When events must be met. Even though you have Create Audit to Always and have not selected 'Save for New Document' for Audit Events an audit will not be created. Maybe you can send me an email with a picture of the 'When' tab of the configuration screen? I have confirmed this to be a bug and is fixed.
