Crouching/Uncrouching while standing on a physics object will cause the object to behave erratically

Crouching/Uncrouching while standing on a physics object will cause the object to behave erratically. Even if the CharacterMovement component has Physics Interaction disabled, it will still effect the physics object in this manner.

User Description:

Whenever I uncrouch on physics object's ledge that object get pushed. Use Flat Base for Floor Checks didn't help.

1. Open the attached test project
2. PIE
3. Jump the capsule onto the physics box
4. Repeatedly press Left-Ctrl to toggle the character crouched/uncrouched
5. Move around on the physics box so the bottom of the capsule is on the edges while repeating step 4

6. Stop PIE
7. Open the 'ThirdPersonCharacter' bp
8. In the Details panel for the 'CharacterMovement' component > Character Movement: Physics Interactions > Disable 'Physics Interactions'
9. Repeat steps 2-5

Results: The box will move and/or flip the player off. It will sometimes be so erratic that the box will fly out of the level.

Expected: A setting to adjust so the physics box has little to no movement while crouching/uncrouching. And if Physics Interaction is disabled on the character, for no movement to occur.
