whi is quickbooks automatically adding negative amounts zeroing out contributions?

I am doing bookkeeping for a church, so the non-profit is set up. This last month, QuickBooks online has started zeroing out contributions. For every contribution posted, there is a negative post mirroring it. This doesn't happen in the bank deposit record. It appears in the Customer's transaction records when the customer is pulled up. It then is zeroing out the amount in the Income account in the Profit and Loss (Statement of Activity). Does anyone know what is going on?
