Hello, LL86. 

Appreciate the steps you've performed to resolve the issue. Let's double-check the template and make sure you're using the default one. Once verified, you set the correct template. We can perform browser troubleshooting. To get started, let's access your QBO account in a private window to see if this is a browser-related issue. This will allow the program to run smoothly without any cache or cookie interference that may cause issues with Intuit sites.

 Here are some of the keyboard shortcuts to quickly open an incognito session: 

• Ctrl + Shift + N  for Google Chrome
• Ctrl + Shift + P  for Firefox
• Ctrl + Option +P if you're using Safari
• Ctrl + Shift + P for Microsoft Edge

Once it works, I recommend clearing your browser's cache to optimize its performance. It will also help delete the information stored in the cache. If you are experiencing difficulty with private browsing, it may be helpful to use different browsers. This will ensure the most secure and optimal experience when using QuickBooks. For additional information on system requirements for QuickBooks, please refer to the following article: System Requirements For QuickBooks.
