I am not sure why the sequence column would say n/a.

If you go to the "Options" menu the "Select Columns" it might be setup differently, just add the columns you need and untick the ones you don't.

Also there is an additional column "Duration" which I didn't add because I think that using procmon will add some overhead so the results are not 100% accurate, but it is potentially a useful metric to compare servers / response times.
