That is the Types View of the Document Type Panel. It displays all the document types detected on the current Batch.
Edit Document Type Template
Click the Edit Document Type Template to create a new document type based on the current document. This will create a new document at the end of the Batch where you can see the template created. Use it to setup OCR Zones and Grids. It can be removed after the configuration is done.
The Edit All Document Type Templates button will perform the same action as the Edit Document Type Template but for all the different Document Types on the Batch, also creating one new document at the end of the Batch for each new document type that you can use to setup OCR Zones and Grids. They can be removed from the Batch after the configuration step is done.
