Something is adding the port back.  It's hard to tell what software is
doing that just by looking at the output of your "grep", because the
"grep" is throwing away a lot of the important context.  Probably, if
you looked at lines near the ones that insert the new rows, you would
see a comment that explains what software is adding the new rows.
