Cygwinターミナルの表示がおかしくなってしまいました。いつもは`home/`など、カレントディレクトリが表示されていたプロンプトが、以下の画像のように`bash-4.4$`と表示されるようになってしまいました。  
どうすれば元のカレントディレクトリが表示されるように戻せるでしょうか？  
Windows10 64bitです。

    # Shell Options
    #
    # See man bash for more options...
    #
    # Don't wait for job termination notification
    # set -o notify
    #
    # Don't use ^D to exit

    #
    # Make bash append rather than overwrite the history on disk
    # shopt -s histappend

    # Completion options
    #
    # These completion tuning parameters change the default behavior of bash_completion:
    #
    # Define to access remotely checked-out files over passwordless ssh for CVS
    # COMP_CVS_REMOTE=1
    #
    # Define to avoid stripping description in --option=description of './configure --help'
    # COMP_CONFIGURE_HINTS=1
    #
    # Define to avoid flattening internal contents of tar files
    # COMP_TAR_INTERNAL_PATHS=1
    #
    # Uncomment to turn on programmable completion enhancements.
    # Any completions you add in ~/.bash_completion are sourced last.
    # [[ -f /etc/bash_completion ]] && . /etc/bash_completion
    
    # History Options
    #
    # Don't put duplicate lines in the history.
    # export HISTCONTROL=$HISTCONTROL${HISTCONTROL+,}ignoredups
    #
    # Ignore some controlling instructions
    # HISTIGNORE is a colon-delimited list of patterns which should be excluded.
    # The '&' is a special pattern which suppresses duplicate entries.
    # export HISTIGNORE=$'[ \t]*:&:[fb]g:exit'
    # export HISTIGNORE=$'[ \t]*:&:[fb]g:exit:ls' # Ignore the ls command as well
    #
    # Whenever displaying the prompt, write the previous line to disk

    # Aliases
    #

    #   source "${HOME}/.bash_aliases"
    # fi
    #
    # Some example alias instructions
    # If these are enabled they will be used instead of any instructions
    # they may mask.  For example, alias rm='rm -i' will mask the rm
    # application.  To override the alias instruction use a \ before, ie
    # \rm will call the real rm not the alias.
    #
    # Interactive operation...
    # alias rm='rm -i'
    # alias cp='cp -i'
    # alias mv='mv -i'
    #
    # Default to human readable figures
    # alias df='df -h'
    # alias du='du -h'
    #
    # Misc :)
    # alias less='less -r'                          # raw control characters
    # alias whence='type -a'                        # where, of a sort
    # alias grep='grep --color'                     # show differences in colour
    # alias egrep='egrep --color=auto'              # show differences in colour
    # alias fgrep='fgrep --color=auto'              # show differences in colour
    #
    # Some shortcuts for different directory listings
    # alias ls='ls -hF --color=tty'                 # classify files in colour
    # alias dir='ls --color=auto --format=vertical'
    # alias vdir='ls --color=auto --format=long'

    # Umask
    #
    # /etc/profile sets 022, removing write perms to group + others.
    # Set a more restrictive umask: i.e. no exec perms for others:
    # umask 027
    # Paranoid: neither group nor others have any perms:
    # umask 077
