Gear VR BP Nodes Inaccessible - UE4 4.14

Hello Devs, 

After updating to 4.14 from 4.13, I ran into an issue accessing Gear VR blueprint nodes.

I am currently using 4.14Release but the issue also appears to be in vanilla 4.14. I had a look through the source files and it seems like the code definitions for the blueprints nodes still exist, but I cannot access them in the engine.

My plugins are enabled correctly and I can build to my devices. The BP nodes are essential for our app to meet the overheating target time. 

How can I go about re-enabling them?

Thanks,

Vince
