I have again repeated it with 6 files named
1.mp3
2.mp3
to
6.mp3


Using bulk rename to rename starting test (01).mp3 gives

file 1.mp3 -> test(2).mp3
file 2.mp3 -> test(3).mp3
file 3.mp3 -> test(4).mp3
file 4.mp3 -> test(5).mp3
file 5.mp3 -> test(6).mp3
file 6.mp3 -> test(01).mp3

Edit -> undo undoes the rename and the files are in correct order

Note: I don't think it is always 1 -> 2 etc yesterday file 6 was being
renamed Track (11) etc
