File naming for playlist or channel downloads

[TheGhost78]

Settings:
General - Folder format: artist:40;
General - Download playlists to one folder: Yes
General - Numerate files in playlist: Yes
YouTube - Filename format: artist:40;\artist:40; - date:%Y-%m-%d; - title:100;

When downloading a whole channel or playlist, a folder is created
[Channel] Name of channel
or
[Playlist] Name of playlist

Currently, the filenames of the downloaded videos are in the format:
<4-digit Playlist Number> - artist:40;-artist:40; - date:%Y-%m-%d; - title:100;
but I think it should be in the format:
<4-digit Playlist Number> - artist:40; - date:%Y-%m-%d; - title:100;

It appears to interpret the backslash of the YouTube filename format as a dash. When downloading channels or playlists, could it be set to ignore anything before (and including) the backslash in the YouTube filename format?
