Hi there, @LaurensPP.
Thank you for providing the details and screenshot to illustrate your concern. I have information why income and expense transactions are missing from the Profit and Loss report.
I appreciate running into all the troubleshooting steps for missing income and expense transactions from your Profit and Loss report. Let's try one more fix for QuickBooks unexpected behavior.
Please open QuickBooks on private browser and check if you'll still encounter the same thing. If this works, you need to clear your regular browser's cache and cookies or use a different browser. This will delete files that are affecting the browsing performance and resolve other data issues.
Before doing so, you need to save necessary information such as login IDs' and passwords.
In case the issue persists, I suggest continuing to rework all your passed invoices as this is the best workaround to do. Just in case you don't have it, review the following article about why income and expense transactions missing from the Profit and Loss report: https://quickbooks.intuit.com/community/Income-and-expenses/Why-are-my-income-and-expense-transactio....
That should provide you with information about missing profit in the reports tool. Let me know if you're able to resolve this matter and if you have other questions. Feel free to drop by again in the Community. I'm always here to answer in any way I can.
