Alright, lets hope I can explain this good enough.
All actions saved in Actions Library are assigned to a random key on my K70 lux keyboard. From what I can see they are all bound to the F1 - F12 key.
For example:
I have discord mute bound on my sniper button (m65 pro rgb) and when I save the mute action to the Actions Library, my F1 button also have the mute action. If I remove the action from my Actions Library the F1 button is back to normal.
