Question Animation parameters greyed out, cant modify them

I add a new animation clip to a gameobject, add transform rotation but then X, Y; Z rotations are greyed out and i cannot modify them

Also i had one rotation animation already made and working which rotates one axis and now instead seeing the transfrom rotation i just see the animation name without any other axis to choose to rotate as i can see when i create a new rotation animation. I just see the animation name and it is always 0 value in any key i set but actually the animation is working dont know why

 

The problem is creating a new clip from an object which already has animations, then it doesnt allow you to change the rotation parameters, but creating an animation from an empty object it allows me to change them
