Steps to reproduce:

1. Open the attached Project
2. Open the "AC_Mage" Animator Controller
3. Double click the Blend Tree "Locomotion Walk" and select the "Blend Tree WALK" Blend Tree State
4. Click on the (═) icon for any of the Motions in the Motions List and observe how the Weight Blue field changes when selecting each Motion
5. Click anywhere where there is free space in the Visualization and observe that all Weights for Motions are visible
6. Repeat step 5 and see that the Weight Blue field is no longer impacted

Actual results: After clicking in the Visualization field where there is no Motion and all Weights become visible selecting any of the Motions with the (═) icon no longer shows their weight, the workaround is to click on the Blue Dots in the Visualization itself, but that might mean that the PosX and PosY fields could be changed by accident

Expected results: Selecting Motions with the (═) icon in the Motions List and selecting Motions with the Blue Dots acts the same no matter if all the Weights have been enabled in the Visualization previously
