Changing focus between monitors partially working

[Amias Burrows]

I've got my Yabai shortcuts setup using SKHD and I've found recently that leaving my external monitor using alt + shift - l doesn't work. It unselects the current application window, but not the application specifically and doesn't move myself over to my main monitor.

Here is my SKHD config file:

  1  Changing window focus
  2                            
  3 alt - j : yabai -m window --focus south
  4 alt - k : yabai -m window --focus north
  5 alt - h : yabai -m window --focus west
  6 alt - l : yabai -m window --focus east
  7 
  8 # Change focus between monitors
  9 
 10 alt + shift - h : yabai -m display --focus west
 11 alt + shift - k : yabai -m display --focus north
 12 alt + shift - j : yabai -m display --focus south
 13 alt + shift - l : yabai -m display --focus east
 14 
 15 # Swap layout              
 16 
 17 alt - a : yabai -m window --swap west
 18 alt - f : yabai -m window --swap east
 19 alt - s : yabai -m window --swap south
 20 alt - d : yabai -m window --swap north
 21 
 22 # Rebalance windows        
 23 
 24 alt - b : yabai -m space --layout bsp
 25 
 26 # Rotate windows
 27 
 28 alt - n : yabai -m space --rotate 90
 29 alt - m : yabai -m space --rotate 270

And here's my Yabai config file.

  1 # bsp, stack or float      
  2 yabai -m config layout bsp 
  3 
  4 yabai -m config window_placement second_child
  5 
  6 # Padding                  
  7 # yabai -m config top_padding 12
  8 # yabai -m config bottom_padding 12
  9 # yabai -m config left_padding 12
 10 # yabai -m config right_padding 12
 11 yabai -M config window_gap 12
 12 
 13 # Mouse settings           
 14 
 15 yabai -m config mouse_follows_focus on
 16 
 17 yabai -m config mouse_modifier alt
 18 yabai -m config mouse_action1 move
 19 yabai -m config mouse_action2 resize
 20 
 21 yabai -m config mouse_drop_action swap
 22 
 23 
 24 yabai -m rule --add app="^(Harvest|System Settings|Calculator|Finder|1Password|Surfshark|AirDroid|Loom)$" sticky=on layer=above manage=off
 25 
 26 yabai -m rule --add app="Visual Studio Code" opacity=0.7

I've usually got it setup so my monitor is left and higher than my main monitor so I use alt + shift - l to move monitors out of my second display:

I have just tried rearranging the displays but I get the same results, I can switch into the external monitor but not out of it again.

Does anyone know how I can fix this or what might be the issue?
