OK....

You have an unmodified ~/.bash_profile and a slightly different
~/.bashrc from my fresh install.  The differences are not significant.

The bottom line is that in ~/.bashrc you have

if [ -f /etc/bashrc ]; then
        .  /etc/bashrc

Which should source the file.  The place where the setting of PS1 takes
place is here....

Basically it is saying....  if PS1 is set to '\s-\v\$ ' change it to
'[\u@\h \W]\$ ' .

So, it would seem, one of 2 things are going on.  Either the file isn't
being sourced or it isn't set as expected.

What I would do is modify /etc/bashrc to ....

  shopt -s checkwinsize
  echo "PS1 is set to $PS1" > /tmp/huh
  [ "$PS1" = "\\s-\\v\\\$ " ] && PS1="[\u@\h \W]\\$ "

And then perform an su -.
