tmux v1.8 current window name bug?

I'm using tmux v1.8 and it sure seems to be acting odd. The session shows just fine. The ID is fine. The date is fine. But the Window name seems broken to me. Maybe something specific with v1.8? I took two screen shots, one with Ubuntu and one with RHEL 7.1. Same config file used on both. Here is my .tmux.conf

# use UTF8
set -g utf8
set-window-option -g utf8 on
bind r source-file ~/.tmux.conf \; display "Fully Loaded!"

# define window split keys
bind | split-window -h
bind - split-window -v

#set mouse features
setw -g mode-mouse on
set -g mouse-select-pane on
set -g mouse-resize-pane on
set -g mouse-select-window on

set-window-option -g mode-keys vi
bind-key -t vi-copy 'v' begin-selection
bind-key -t vi-copy 'y' copy-selection

bind h select-pane -L
bind j select-pane -D
bind k select-pane -U
bind l select-pane -R

# setup Status Line
set -g window-status-format "#I:#W"
set -g window-status-current-format "#I:#W"

set -g automatic-rename on
set -g status-interval 1

# default status bar colors
set-option -g status-bg colour235
set-option -g status-fg colour11

# Default window title colors
set-window-option -g window-status-fg colour240
set-window-option -g window-status-attr dim

# Active window title colors
set-window-option -g window-status-current-fg colour10
set-window-option -g window-status-current-bg colour235
set-window-option -g window-status-current-attr dim

# clock
set-window-option -g status-right " %H:%M %d-%b-%y "
set-window-option -g status-right-fg colour166 

# message text
set-option -g message-bg colour235
set-option -g message-fg colour7

## END ##

And I have the two images added as well.

You'll see that in Ubuntu, also running v1.8, I have vim and top running and the status bar reflects this. On rhel I am running vim twice and it shows my user@host.

These settings:

# setup Status Line
set -g window-status-format "#I:#W"
set -g window-status-current-format "#I:#W"

specifically the "#I:#W" should show the Index : Window Name. Can't get it to actually show the Window name.
