There are two reasons why your transactions are in reverse. Let me share them with you and help you sort out your CSV file.
First, you have both negative and positive amounts in one column. Second, the payments and deposits are mapped incorrectly.
If If you've uploaded the files with the amounts in one column, you need to switch it to 2 columns. This way, your transactions will be divided into debits and credits.
If you're using four columns in the CSV Files, I suggest you make sure that when you upload them, payments are map under Credit, and deposits are under Debit.
