Classify Document outputting "Unknown" IntelligentOCR activities

I am using the IntelligentOCR activities in UiPath Studio, I trained a classifier (.clf) file in Abby FlexiLayout Studio and it is correctly classifying documents and images. But when using it in UiPath Studio it is resulting in “Unkown” always.

The result of “Classify Document” is Unkown always:

I am facing the same issue, did anyone find a solution? Is it because of the new Studio version? I think #uipath should put put some training for Abby & IntelligentOCR activities.

Can anyone please help in this?

Even iam facing same issue…if header is in first page its recognizing document definition …if not it throws unknown document definition can some one help us on this
