Invoice approvals have incorrect submitted by person

Summary:

Payables Invoice Approvals - For some submitters the WF shows the incorrect submitter

Content (please ensure you mask any confidential information):

Invoice approvals can be submitted by a few people. The main uswer who did the testing does not have the issue described below but two other users do.

The problem does not reproduce in the test system.

Description —-

User Maria X creates and invoice and initiates approval.

This goes to Maria's manager and gets approved OK.

However in Approval and Notification history or viewing the Approval in Transaction Console the WF shows the submitter as RSMASTER which is a general Admin / Superuser account that is not connected to Maria.
