Hi, JohnWerth.
I appreciate the detailed information you've provided about the Net 30 date in QuickBooks Desktop. Let me help sort this out.
You'll want to make sure your QuickBooks Desktop is updated to the latest release. This way, we can ensure your software is packed with the latest features and fixes.
However, if you have the same issue, I suggest running the Verify Rebuild Utility Tool in QBDT. This tool scans your company file for errors and fixes them right away.
I'll show you how:
To Verify:
- Go to the Window menu and select Close All.
- Then, go to the File menu.
- Select Utilities.
- Click Verify Data.
To Rebuild:
- Go to the File menu.
- Select Utilities.
- Click Rebuild Data.

Please reach back out to me here with any additional information on the issue, so I can get you taken care of.
