NI 9401, delay in sending output signal in different channels

I was messing around with a 9401 using LabVIEW's built in digital - continuous output example vi. I noticed that for every channel there is a delay from when the vi is run and the signal actually being sent. On channel 0 there's no delay but on channel 1 there's a delay equal to the pulse width and on channel 2 the delay is twice the pulse width, for channel 3, 3 times ect. 

Is this something built into the 9401, or is there something in code doing this that I missed? I plan on using 1 second pulses and having several second delays on some channels is not preferable.
