SU2 or CGNS grid - Sources are not listed as Unspecified in final generated mesh
 

I am trying to make source at exit of nozzle to capture finer shear layer area as seen in attached images. And I see sources does that job like creating vortx or shear layer refinement. I am trying the same but seems like when I do export into either .SU2 or .CGNS in both cases it says unspecified markers whereas I dont have unspecified markers in my boundary conditions when I did it as attached in images. So do we need to anything specific to these sources which is missing here? Appreciate your help

I am trying to refine my Shear layer starting at the exit of nozzle. Appreciate your thoughts if there is any other way to make this area refiner (rather creating connections and doing them, which I can., but there must be smarter way). Thank you for your help!
