After correcting OCR in the OCR Editor, I exported the results as a PDF as a searchable PDF. Opening the output in the FR viewer shows the corrected OCR, but if I open the output PDF in the OCR Editor (let's say to make further corrections), none of the corrections are retained. In the OCR Editor, I can only re-recognize the PDF--all corrections disappear.
Am I missing something? Is there a way to retain the edits in a way that the OCR Editor would recognize, or is it necessary to save the OCR "project files" in order to make further edits later?
