No surprise here, my bank app mess up dates too sometimes, so you need to set the transfer 2 days later, then you need to wait the cut off time, that makes today +next 2 days to get the cut off time so 3 days total, if the cut off day is Friday, you are screwed because Saturday and Sunday banks are closed and don't work, so you go to Monday, at that point a bank transfer takes up to 3 days, that makes 7-8 days total. It's the norm

If you want immediate transfers they are enabling (at least here) fast bank transfer if both banks (sender and receive have it enabled) so the transaction is immediate like here on hive
