Manual Sales Event - System changes the past event name to the new event name

When the user uses a past/existing Sales Item Event as the basis to create a new event and changes the name of the new event, the system also changes the name of the past event.

With Manual Events we create some form of versioning, if the user changes the Name, a new instance (profile) is created.
If the adjustment % is changed, that too generates a specific version of the same event.

Some of my findings/testing: https://docs.google.com/document/d/1Ns0jc7Cf75KemmLk8IrlezJ1ZK9hTCT2nE3CzJNrzK0/edit?usp=sharing

Reproduction Steps:
Hover over a past event to notate name
click Add event for current/future day
Select the event notated of the past
Click Next
Change the Event Name to something different
Enter Adjustment
Save

Expected Results:
Past event should keep its name

Actual Results:
Past event name has been changed to the new event name.
