I did the preview thing and still, my file name has extra things added to it. I named the file: 0-DRN-385398-1.pdf, but the name it was given is 0-DRN-385398-1_20211022_0001.pdf. Imagine scanning in all the documents needed for a 40-year land record search and having to rename all those Deeds, Deeds of Trusts, Easements, and Plats. I told the program what to name the file. There is no option to uncheck adding the date and a four-digit number to the end. A program should not add to a file name without the option to turn it off.
