Leave the '/xxx' part out of the 'track' field when using it to rename the music files

If I want to rename the files of an album that has in the track field the following (quite normal) values: 01/15, 02/15, 03/15,…15/15
and as template name I specify “%TRACK - %ARTIST - %TITLE”
Audio Catalog wants to rename my files to:
01/15 - ….
02/15 - ….
…
14/15 - ….
15/15 - ….

which of course doesn’t work since / is an invalid character in a filename. Imo, you should leave out the “/xx” part of the track field when applying to the file name.
