Hi thehonestskillet,
In the Products and Services tab, QuickBooks only shows all items (inventory, non-inventory, services, & bundle) for expense and sale transactions. There shouldn't be any expense or sales transactions on that page.
Let's check if this isn't a browser-related issue. This way we can isolate the issue. Can you try to access QuickBooks Online using a different browser? Are you still seeing the expense transactions in the Products and Services page?
Please come back with more information, thehonestskillet. Thanks in advance!
