You can perform browser troubleshooting to resolve the unexpected behavior with your invoice, @smcconnell2.
To begin with, I appreciate the effort you've put into reviewing your templates, memos, and invoice fields. To address the unexpected text appearing on your invoice, I recommend clearing your cache and Intuit-specific cookies. This action can help remove any outdated or corrupted data causing this issue. You can also use another supported browser to access your QuickBooks Online account as an alternative option.
