I have a working Quick Fields configuration utilizing Universal Capture from a network share. There are only three classifications. I have uploaded this configuration to our Quick Fields Server, and it is visible in Quick Fields Scanning. When I begin the scanning in QFS, it spins for a few minutes, then quickly dumps all files into the Document list as Unidentified. Manually assigning a document class works as expected. I have attached a screenshot for both Quick Fields and Quick Fields Scanning showing results from the same configuration.
Of note, my Zone OCR is in Pre-Classification processing, which is what's used to perform token identification on each classification.
