I hear your sentiments, @stheobald.

Currently, we received reports that some users are having issues recording their purchase order (PO) correctly. Rest assured our engineering team is working diligently to fix this. 

In the meantime, you'll want to redo the troubleshooting steps you've performed by marking the PO closed and saved. Then marking it again as open then saved.

Moreover, I suggest contacting our support team so you'll be added to the list of affected users. This way, you'll be notified of any news the issue is solved via email. 

In case you need to record a refund from your vendor, you can utilize this link that can walk you through the steps: Record a vendor refund in QuickBooks Desktop.

I appreciate your patience while we're currently working to fix this. If you have any other concerns or questions about PO, please feel free to tag me in your reply. I'll be here ready to assist you anytime. Keep safe!
