Found in 4.20 CL# 4369336. 4.21 CL# 4613538, 4.22 CL# 4751672

1. Open the Editor
2. Import the attached FBX
3. Create a material like the attached image but set the TextureCoordinate Nodes Coordinate Index to 1
4. Apply the material to the imported mesh

Results:
It appears the BumpOffset node is still partially relying on Coordinate Index 0

Expected:

Incorrect Behavior would not occur when the Coordinate index is above 0
