Question VRChat Model not walking in unity

So, I downloaded an avatar off of VRModels called 'Rindel'. Upon the first time putting it in unity and to the game, everything was fine. But when I readded the model after adding toggles, there isn't any walk animations in game. I didn't mess with any of the locomotion on this avatar and im having the same issue with another avatar. I'm a beginner to Unity and avatar uploading, so please keep answers simple!
