Convert> Filename > Tag adds space before Title

I use Adobe Soundbooth to create my mp3 files into a folder. My file naming is:
01 - Track 1
When I convert the Title has an extra space before the words like " Track 1".

Also, if I set a title to "Peanut Butter/Jelly", then use the convert Tag to Filename the slash is removed. I'd like to make that replace with and Underscore. Is that possible?

Thanks.

Use $trim($replace(%title%,'/','_')) to remove leading and trailing spaces and replace the slash with an underscore
