Hi mikemoran19,
Thank you for visiting Quickbooks Community.
First, to isolate the issue, if you are using Quickbooks Online mobile app, let us try to uninstall and reinstall the app to make sure that you have the latest version of Quickbooks Online mobile app.
Once done, let us try to check on the invoice paid to see if it shows the amount allocated. If you encounter the same error, we'd highly suggest you contacting our QuickBooks Online Support via Chat or Phone Support Hotline on this link: https://help.quickbooks.intuit.com/en_AU/contact
