Morph Target Flickers When Toggled and On Collision

-Can not currently open mesh due to lack of skeleton but user sent in his entire project/game so it had to be stripped down due to file size. Message/Email me if the skeleton or entire project is needed.
-There were several variables that could have been causing the issue
-Damage is initially done when the car collides with meshes in the level
-There were roughly over 40 material elements

1. Download attached file
2. Play in Editor
3. Press 3 on keyboard
4. Toggled rapidly on keyboard between numbers 1 and 2
5. Notice mesh is flickering
6. Shift + F1 and then Eject to get a better look at the flickering mesh

Expected: Mesh does not flicker and instead just maintains the damage
Result: Morph target flickers in and out of existence
