Mec Anim transition Bug?

Good Day,

I have created a simple transition from an animation to another using the animator state machine for mecanim.

I also modified the transition in the inspector by moving the begin transition slider and the end transition slider.

I saved the scene, and all the information has been saved.

When I close unity, open it again and the scene and start playing the scene, the transitions play as default but do not show the modified behavior I edited before. Also, and thats the most obvious thing, the progress bars for the animation nodes in the animator window (blue progress bars in the nodes) do not appear.

Everything comes back as I click the Character node in the Scene Hierarchy once, and stays as it should.

Is that a bug or known issue?

Cheers Werner
