Linear Color Struct values are changed when upgrading from 4.26.2 to 4.27.1

It seems that changing the value to something different than the default of a Linear Color Struct variable, results in the value being changed when upgrading the project to a new engine version. This is not exclusive to the DrawDebugCamera node as it seems to happen with any node that has a Linear Color Struct input node.

1. In UE 4.26.2 create a new blank game project
2. Open the Level Blueprint
3. Place a DrawDebugCamera node
4. Split the CameraColor struct pin
5. Set CameraColorA to 0
6. Compile and save the Blueprint
7. Load the project in UE 4.27.1
8. Open the Level Blueprint

RESULT:

The value of CameraColorA reverts back to the default value of 1.0

EXPECTED:

The values are maintained when upgrading to a newer engine version
