AO missing 1st output when triggered with AI/StartTrigger

Hi,

I have MIO-16xe-10 card, and am trying to start output and acquisition simultaneously using daqmx. I have copied most of the diagram from the Multi-Function-Synch AI-AO.vi example (see the attached vi). When I try to run it with only 1 iteration (that is, when the AI-AO happens right after the configuration) it works fine. But when i do 2 or more iterations, from iteration 2 on it "forgets" to output the first point to AO. I can see it on the oscilloscope, too.

The question is: why?

Thanks in advance for your help,

-Alex
