I had the same problem, using mac mojave and a 3. something version of calibre, for some reason didn't like the names of the files. When I changed the name of the files everything started to work fine. It's a non-tech solution but it worked for me. Once I found a file name the laptop liked, I just use that name and change the date to correspond with day of back-up. I have had no problems since. So just play around with name of file.
