Hello there, @cheryl8736.

Thanks for sharing your observations with the Purchase Orders today. We didn't see this coming. 

It could be that you're data is going through integrity issues. Hence, the POs are sending twice.

Let's run the rebuild tool in QuickBooks Desktop to repair issues in your company file. Ensure first that you're using most updated QuickBooks Desktop version. Then, follow the steps below:

1. Click File, Utilities, then Rebuild Data.
2. Allow it to load, then select File again, Utilities then Verify Data.
3. Click OK as soon as you get the message "Rebuild has completed".
