SetCustomDataValue Returning False

[Floh]

I am creating a series of actors that have instanced static mesh components. Upon creation of a new instance, I am attempting to assign a custom data value to that instance.

The print after always returns false, and the value within the material always uses its default value.

Is there a limitation here that I am missing? If not, what can I do to debug this?
