Hello there, Alison. The reason these are appearing now is that the Product/Service Detail report tracks any transaction tied to your Income and Expense accounts, even if a specific item wasn't selected.
When you add a transaction directly from your bank feed and categorize it to an account such as Sales, without picking a specific product or service from your list, QuickBooks still includes it so your report totals match your Profit & Loss statement.
The system is simply flagging these transactions because they aren't linked to a specific item yet, so it labels them as Not Specified.
To fix this, when you're reviewing your bank feed, make sure to pick a Product or Service from the dropdown menu instead of just choosing a Category or Account. This tells QuickBooks what was sold, so it can track your items accurately on the report.
Let us know in the comments if you have follow-up questions.
