N5182B Sequence creation isn't conveying markers from segments

I'm using the N5182B to sequence waveforms together.  I create the waveform files using matlab and I also create a marker file for each waveform.  When I put the waveforms on the N5182B I move both files to the correct directory.  I can load the waveforms on the sig gen individually and using the 'display waveform and markers' softkey I can observe that the marker file is working as I expect as well.  They also fire the event pins correctly when I play them.

My problem is that when I attempt to sequence these waveforms together, the resulting sequence has no markers.  I have the 'markers' parameter of the sequence scpi command set to 'ALL' so it shouldnt be an issue with the markers just being turned off.

I tried this process before where instead of using a marker file, I would load the waveforms into volatile memory then add a marker before sequencing and those markers made it into the sequence as expected.

Is there some extra step I need to take between having a waveform/marker file combo that gets loaded into volatile memory and sequencing to ensure that my sequence will retain the markers from the marker file?
