List Fields will never change Lotus Notes documents without asking you explicitly.
In order to keep that promise, List Fields maintain a change log containing every change you do. As soon as you do anything that might lead to a change of the original document, the change log pops up automatically. For each change you do, List Fields creates at least one so-called change log entry. For example will List Fields create 1 log entry when you add a new field. If you solve a replication conflict, List Fields will create several log entries.
You find the change log as a pane in the Information Area. Read more about the Change Log here.
