Resolve "Batch has been Modified or Back/Forward Synchronization Failure" Error in Lighthouse Transaction Manager

What is causing this Error?

The error stating "Batch has been modified or a BACK/FORWARD synchronization failure - view and verify again" occurs when:

• A user makes edits/changes to transaction details while another attempts the batch closeout. 
• The user edits a transaction, selects the back button in the browser, and attempts to submit the batch with totals that do not reflect the adjustment just made.
