"set|grep PS" Produces more data than I can deal with visually,

From box6 which works as expected:
[ -e /etc/sysconfig/bash-prompt-default ] &&
PROMPT_COMMAND=/etc/sysconfig/bash-prompt-default
From Box9 with the strange prompt:
[ -e /etc/sysconfig/bash-prompt-default ] &&
PROMPT_COMMAND=/etc/sysconfig/bash-prompt-default
.
