Welcome and thanks for dropping by the Community, @harmoniousbalanc.
To check if the browser's cache and cookies are causing this odd behavior, try signing into your QuickBooks Online (QBO) using a private browser (incognito).
Here's how:
- Press Ctrl + Shift + N (Google Chrome).
- Ctrl + Shift + P (Firefox).
- Control + Option + P (Safari).
Once logged in, try to change the dates on the Profit and Loss report.
