Training Model Invoice Extraction

Hello there Community

I made a Workflow very similar to the one presented in the Uipath Academy course “UiPath RPA Platform 19.4 Updates - Intelligent OCR Document Processing Framework”. I use the validation station to verify the extracted information and try to train the model, however, when I select the same invoice I used for training the detection is always the same.

Is this feature already working? How can I make it work?
