Unflatten from JSON resets all values when Enum is replaced by Cluster #54

I encountered an issue when using the "Unflatten from JSON" VI.

In a previous version of my JSON structure, one of the keys was associated with an enum. In the new version, that same key is now associated with a cluster.

I expected the Unflatten from JSON VI to convert the remaining keys correctly and set the new cluster to its default values. However, all the values in the resulting structure were set to their defaults, even though some keys were present in the JSON.

Is this the expected behavior, or could this be a bug?
