Lightroom Classic Catalog issues
I recently updated to the Lightroom Classic. I am on the Adobe Photography plan, so I always have the latest updates from CC versions. The Lightroom Classic has properly converted my 2015, 2016 and 2017 photos into the new catalogs. However, my 2013 and 2014 catalogs are not so easy. Both my 2013 and 2014 Catalogs are stored on my Seagate 3TB device. Through some luck, I was able to get the 2013 catalog to be converted. The 2014 Catalog is not yet converted. With following the steps from Lightroom Classic, the catalog seems not to convert as needed. Below are the screen shots that is repetitive in trying to convert.


Keep in mind as I followed the same process for converting the 2013 catalog and had success. So I am confused.
Below is my computer info if this helps in understanding my operating system.

Any help and/or suggestions would be greatly appreciated so that I can finish the conversion process.
