I get these emails at 6:01am-6:05am containing "x Note(s) did not issue"

When notes are note issued is a bizarre to me that those notes amount to not immediately show up in my "Available Cash" amount.
Instead it seems to happen throughout the day as I sometimes get orders from BlueVestment throughout the day. (i.e. day starts with < $25 "Available Cash")
