I record 24/7 in 1-hour segments, no problem.
In your second snapshot you have the limit set to ONE MINUTE - 0.01.00, which seems very short, should it be ONE HOUR - 1:00.00 ?
That shouldn't make any difference, tho, your recording should automatically resume - as you haven't had any solutions here, do write to Support, they will respond - especially as you are within the refund period 😉
