Glad to see you here in the Community, user58666.
I can help you with adding purchase order numbers on the delivery note that you'll be creating.
You can customise the invoice by adding another field and identify it as Purchase Order. Once you've created a Delivery Note out of it, purchase order number will now be included in the delivery note.
Here's how to customise the invoice:
Purchase Order is now added on your invoice. I've also added screenshots below for your reference.

That should do it. Let me know if you need further assistance in creating a delivery note. I'm always here to assist. Have a great rest of the day.
That's weird, TonyPham.
Let's use a private window to check if the error is browser-related. Just press Ctrl + Shift + N on your keyboard to go incognito.
Now, log back in to QuickBooks Online and go back to the adding fields. If you're able to proceed, let's clear the browser's cache. Check this article for the detailed steps: How do I clear my browser cache and temporary Internet files?
You can also try to use a different browser.
Let me know how it goes so I can assist you further if you need it.
