How do I remove gap between multiple window status in tmux status bar?

I would like to remove the gaps between the multiple window status in tmux status bar

but I have no idea how, here is my setup

## current window and pane indices at bottom left corner
set-window-option -g window-status-current-format "\
#[fg=colour239, bg=colour202, bold] #I, #P \
#[fg=colour239, bg=colour214, bold] #W \
#[fg=colour214, bg=colour237]"

## other windows and panes indices at bottom left corner
set-window-option -g window-status-format "\
#[fg=colour239, bg=colour117] #I, #P \
#[fg=colour239, bg=colour118] #W \
#[fg=colour239, bg=colour237]"

Could you please help me with this issue? Thanks in advance!
