Duplicated Parameters in a MPC cannot be used always return source results

When you duplicate a Parameter in a Material Parameter Collection instead of adding a new Parameter, the duplicated parameter always returns the same results as the source no matter the value entered in the MPC.

Also reproduced in 4.8.0 Launcher and Main Promotable-CL-2581018

1. Open QAGame Editor
2. Create a Material Parameter Collection
3. Add a Scalar and Vector Parameters with default names
4. The Scalar should be 0 and the Vector should be set to (1,0,0)
5. Duplicate each parameter and name the results Test01 and Test02 respectively
6. Assign a Value of 1 to Test01
7. Assign a Value of (0,0,1) to Test02
8. Create a New Material
9. Assign Scalar00 to Metallic
10. Assign Test01 to Roughness
11. Assign Vector00 to Base Color
12. Assign Test02 to Emissive Color

RESULTS: A Smooth Red with Emissive Red

EXPECTED: A Completely Rough Black with Emissive BLue Glow
