Use of the Fresnel Material Property requires manipulation in the code editor

Use of the Fresnel Material Property requires manipulation in the code editor, which subsequently can break pre-built components in DS. 

Snapshot: Snapshot 107

Details:

• Fresnel Property Sheet Value range appears to be from 0 - 6 with increments of 0.1
• Unclear what other properties in the material editor influence fresnel other than lighting (roughness, metal, clear coat) - While I was able to achieve a basic example using Fresnel, when I tried to do this again with another example I have been unable to achieve any noticeable effect.
• Adding component libraries from the component panel appears to include import version numbers of 6.5 essentially breaking the new features.
