Material Parameter Collections are not working on Android v 5 phones from 4.11

Material Parameter Collections are not successfully passing stored values into Materials when packaged for an Android Phone with an OS version of 5. Both version 4 and 6, correctly use the MPC.

Note Regression, MPC is correctly working in 4.10.2 and broken as of 4.11 Preview 1

*Quick Repro: Open Attached Project and Launch on Android Device with Version 5*

1. Create a Blank Project with No Starter Content
2. Add a Cube to the level in front of the player starter
3. Create a Material Parameter Collection(MPC)
4. In the MPC, Add a Vector Parameter called Color with a value of 0,1,0,1
5. Save and Close the MPC
6. Create a New Opaque, Unlit Material
7. Assign the MPC Parameter Color to the Emissive Color Input
8. Save and Close Material
9. Apply the Material to the Cube
10. Save the Level as Test
11. Set Test to open on Editor and Game Launch
12. Launch on an Android Device using OS version 5

RESULTS: Cube Renders Black

EXPECTED: Cube Renders Green
