When running the coupled model, the 'p_top' attribute in namelist.input disappears.

As described in the title, when I run the coupled model, the ‘p_top’ attribute in namelist.input disappears. I run ./submit job.sh, and the namelist.input file is copied to the rundir folder. However, the p_top_requested attribute contained in namelist.input is missing. I’ve placed the file below.

The namelist.input located in the outputs_real folder.
namelist.input.outputsreal.txt
namelist.input.base.complete.txt
namelist.input.prep.BENGUELA.txt
namelist.input.real.BENGUELA.txt

The namelist.input in the rundir folder.
namelist.input.txt
