I totally get the frustration, Barbara. Since this happens intermittently, your browser is likely stuck with outdated data.
If the report starts acting up, perform a quick hard refresh by pressing Ctrl + F5 (Windows) or Cmd + Shift + R (Mac). This will force the browser to reload the page from scratch.
If the issue persists, consider using a different supported web browser or accessing your account in Incognito/Private mode. This clears out any sneaky cookies or extensions that might be interfering with the Profit & Loss (P&L) view.
If you have any further questions, please don't hesitate to revisit this thread.
