Updating user via import process generates unexpected data on Audit Log

Issue Summary

Unexpected data generated on Audit Log after an import process to update users.
When users are updated (Email address, City, and Enterprise Hierarchy, for example) via the Import process, an "extra line" (with the previous email address) is added to the Audit Log.

Steps to Reproduce

1. Jira Align Administrator > Access Controls > People
2. Export user to be updated
3. Edit the file and change the email address and other fields, if it is required;
4. Import the updated file

Expected Results

User record updated accordingly

Actual Results

User record is updated accordingly but an "extra line" (with the previous email address) is added to the Audit Log.

The same behavior was reproduced on alignsupport.jiraalign.com (for the user below) following the same steps described.
https://alignsupport.jiraalign.com/MasterUserList?Programs=558,556&Releases=363,422&FilterID=356&MasterUserID=661824

Per Internal Escalation, the extra email address is indeed confusing and it doesn't make any sense as to why it is there in the audit log.

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available
