Funeral policy debit order query

So I decided to change the date for my funeral policy on the App from the 27th to the 2nd and another from the last day of the month to the 2nd, Capitec then decides to debit my account on all four dates, please make it make sense why a debit would be due on the 27th as well as the 2nd and another on the last day as well as the 2nd? And then it shows that one of my policies is in arrears? How did they get to this?
