I am using a fixed prefix (eg:lake) & an automatic suffix rename for my pictures
Some of my folders have a text file (lake xxx jan 2020.txt) or a thumbnail that should not be renumbered
When numbering without these files, everything is ok. When I inadvertently include them in the renumbering list, and have to go back one line, the process fails, both files remain unnumbered. After advancing one line, both are renumbered.

if i deselect several files and very slowly advance, the numbering process is ok.
Unfortunately, reducing the window where the files are, and showing only one file ahead, makes this a very common error.
