Currently ``name`` field that holds the action type is recomputed each time duplicated leads are updated. However duplicated leads are often updated notably each time customer action (create / link / do nothing) and chosen customer are updated. As ``name`` compute method is mainly present to replace a default value its compute method is updated so that it nows compute only when not having a value. Once having a value user choice is kept.
