"Set Animation Mode" creates multiple instances of the AnimBP

Changing the Animation Mode repeatedly creates a new instance of the AnimBP being used every time you switch back to the Animation Blueprint mode.

Example Project: [Link Removed]

1. Download and open the example project
2. Open the ThirdPersonAnimBlueprint and drag it to the side
3. PIE
4. Alt tab so that you get mouse control back
5. Wait a few seconds as the character BP switches Animation Modes back and forth
6. In the AnimBP, drop down the debug filter

Result: Multiple instances of the AnimBP have been spawned while switching back and forth.
Expected: Some sort of cleanup after you switch away from AnimBlueprint mode
