Audit - Recording "Local Client" as the user who made a change on a calculation

Hello!

When I am creating a calculation and have enhanced audit enabled, I can see that the audit recorded an ADD message with a timestamp and the user name who made the changes (me in this case). When I am making a change to the same calculation and I hit APPLY, two messages are created: one UPDATE message with timestamp and user (me) and a second message with the action that cause the change (e.g., calculation configuration updated). However, the user that appears on this second message appears as LOCAL USER. See screenshot. 

 Shouldn' t the user who made the change that appears on the UPDATE message (below)? See the 1 milisecond (rounded) difference between messages. 

 Thanks!
