Actually, the fact that it works in a calibre template is probably a bug.

Calibre removes slashes in template items, with the exception of a leading slash in a tag. The probable bug is that composite columns (columns built from other columns) don't have that processing (slash removal) applied to them. There isn't a good reason why composites should be treated differently from custom text or standard columns. However, I am not going to fix that probable bug because it has been there too long and people (like you) might depend upon it.

I am not willing to change CC's template processor to allow slashes in fields by default because such a change could break things. Consider a title like "My Magazine 2011/10". That slash should not (must not?) indicate a new directory level. Neither should a series like "Coffee/Tea". However, I am willing to add a format specifier that tells CC to not remove slashes for that template item, something like

Code:

{#mycolumn:allowslashes}

If #mycolumn contains "aaa/bbb", title = "Foo" and authors = "Blogs, Joe" then the following template

Code:

{#mycolumn:allowslashes}/{title} - {author}

would produce

Code:

aaa/bbb/Foo - Blogs, Joe

Leaving out the allowslashes format specifier would produce

Code:

aaa_bbb/Foo - Blogs, Joe

if #mycolumn is empty then the template would produce

Code:

Foo - Blogs, Joe

Do note that using calibre's template will probably create problems if you use CC's content server or cloud connections. See How do I get the same file names in CC no matter which connection I use? for more information.

EDIT: also note that if you use a composite column in a CC template and also use the cloud connection then you almost certainly want to use the calibre plugin that stores the composite column values for CC's use. See When I look at book details using the cloud connection my custom columns "built from other columns" are missing. Why? for some explanation.
