Why are we still unable to get NAME from document classification results?

Hate to break it to you Paul.
But that data has always been in the extraction result…

Assuming you have the datatype of UiPath.DocumentProcessing.Contracts.Results.ExtractionResult you have the following.

If you use the modern activities you can still get this information even though the data types are different, but I assume you are on the older Windows Compatible ones and not the cross platform ones.
