Expense type in ER and Expenditure type in AP are different

Summary:

Content (required):

Expense Report have a line with Expense Type - AAAA <<created manually by user>>

Process Reimbursement is run.

AP Invoice is created with the Expense Report number.

But, AP Line 1 - Distribution line - Item - Project details - Expenditure Type - BBBB <<it should have been AAAA>>

The invoice line distribution was not modified manually.

Have verified all other expense reports that have this Expense Type - AAAA and except for this particular case, all are showing correctly as AAAA in AP invoices.

Also, in Non-Prod, created an ER for the same user with exact same details and it is working fine, no issues. AP invoice is showing the expenditure type correctly as AAAA.
