Thank you for providing detailed information about your concern, @mkm2.

Since the 3 transactions are still showing on the unapplied cash payments considering that they have the same date, I suggest contacting our support team so that they can check on the transactions to verify the problem. They have tools to remotely view your end and to secure your personal information.

You can also seek help articles, whenever you encounter some QuickBooks problem. Some of the articles will give you tips in running your business and some are about the issues in QuickBooks with solutions. 

Feel free to post here if you have concerns with QuickBooks. Community is always one post away. Stay safe.
