The option "--skip-preview-namelist" doesn't seem to work

[dayon]

In the recent CESM2.1.*, the last step of running case is "./case.submit". when seeing the help document of ./case.submit, a description of the option "skip-preview-namelist" is listed as follows:
--skip-preview-namelist
Skip calling preview-namelist during case.run.

however, it does NOT seem to work. because whether I add or not add this option, the implementation process always like below. Then, this series of "calling ..." seem to also occur when I only type "./preview_namelists", it seem to be odd. Could scientists give some advice? Thanks in advance.

preview_namelists gets called automatically during (1) case.build, (2) case.submit, and (3) case.run stages. Even though the "--skip-preview-namelist" flag is to be specified at (2) case.submit stage, it only prevents preview-namelist calls during the succeeding (3) case.run stage, i.e., during the actual batch job.

Thanks for your reply, Alper Altuntas.
