[Nitro]

In calibre I have custom column called series_id, it contains short form (abbreviation) of series name. Calibre also created field called series_id_index. Everything works nice when I'm sending files to my devices, but... When I'm trying to set the file naming scheme for CC it works bit different than in calibre.
Filed {series} contains only series name, by {#series_id} includes also number in it, so I have "HP [1]" where I should have only "HP". Moreover {#series_id_index} is unknown to CC.

Is it bug or it should work like this?

My scheme: {author_sort}/{#series_id}{series_index:02%d| - | - }{title}
