The settings following that text are global, i.e. they're not for the individual animation type. These settings define the animation types for some standard animations, e.g. idle, walk, run, damage, etc.
Make sure these settings are correct and your combatants have animations set up for the types you need (e.g. idle, run, etc.).
Also, since you're using legacy, make sure your animation's layers are set up in a good way - e.g. the game tutorials use -1 for idle animations, 0 for movement and 1, 2, etc. for more important animations like attack, evade or damage. An animation playing on a higher layer will hide animations on lower layers, e.g. the idle animation could be playing all the time and running hides it due to being on a higher layer.
If all of that seems to be in order, I'd probably need a test Unity project with your setup to look into it.
