Negative signs continue to appear on expense transactions in QuickBooks (QB) Solopreneur, Tbarranti.
Income amounts are displayed as positive numbers without a plus (+) sign, while expense transactions are shown as negative amounts with a minus (-) symbol. I've added a screenshot below for your reference.

Also, please ensure that refunds are correctly recorded as expense transactions.
If your refunds are categorized as expenses but don't show a negative sign before the amount, clear your browser's cache to remove any stored data that might be causing the issue. You may also consider using another supported browser if the problem persists.
