Cannot profile kernel properly.

Hello, following picture is a screenshot of profiling the vision/watermark example of SDAccel, ver. 2018.2

I'm running the example on a 2018.2 SDx due to compatability issues. 

 

The question is: Isn't the 'compute unit' part (the three lines below) supposed to come AFTER the blue apply_watermark line, 4th from the bottom?

Or at least, AFTER the clEnqueueNDRangeKernel queue at the second from top?

 

I believe that 1) There is a misunderstanding of how profiling works/how kernel enqueues are done, or 2) I've done something wrong when setting the profiling.  What might this case be?

Help would be appreciated Thank you.

I think they are supposed to be at the same time. There seems something wrong. 

You may try newer version or other target mode to see any difference if possible.
