Transition Conditions

Hello, I am new to Lumberyard and have recently been trying to understand how the 3d modelling works in Lumberyard and how it interacts with motions. I had created an anim graph that was working fine with the starter model and its animations. I had been following the tutorials until I started experiencing issues with the motions no longer running. I cannot active any nodes, I cannot create or use any pre-existing transition conditions. Forgive me if this is something simple but I have been unable to figure out what is casuing this issue and how to resolve it.

Thank you for the help, Dogforpm
