Thanks Steven.
I followed the steps and the issue is still happening.
Here are two examples of the file names:
01-Jeff Buckley-Mojo Pin_1 and 01-Jeff Buckley-Mojo Pin
02-Jeff Buckley-Eternal Life_1 and 02-Jeff Buckley-Eternal Life
Here is a link to the zip.
Also, note that I now get an error when I click on the Organisation button on the auto-sweep section of the settings:
