Problems scraping TV Shows from within subfolders

I’m just trying out Kodi on my PC before deciding to go for a full hardware-based solution, and so far it seems pretty good and very configurable. I’m having some problems scraping TV shows though, where it does not seem to drill down through the directory structure as I would have expected.

I have current TV shows saved inside their own subfolders within my main ‘TV’ directory on my NAS, which after a bit of fiddling with the naming system seems to be working broadly correctly.

Older archived shows (which I don’t want cluttering up my main TV directory on the NAS) are all saved in their own subfolders inside a separate ‘miscellaneous’ subfolder within the main ‘TV’ directory. However no matter how I try naming the subfolders and files within that miscellanous folder, nothing at all seems to get scraped. The filenames seem correct as per theTVDB guidelines.

For example, in the (partial) list below, the top level folders work – including various sub-folders located inside ‘Doctor Who’ and ‘Once Upon a Time’ – but I get nothing at all scraped for the ‘Blake’s 7’, ‘Red Dwarf’ or ‘Babylon 5’ folders:

/TV/Doctor Who/ (with various subfolders)
/TV/miscellaneous/Blake’s 7/
/TV/miscellaneous/Red Dwarf/
/TV/miscellaneous/Babylon 5/
/TV/NCIS/
/TV/NCIS New Orleans/
/TV/Once Upon a Time (2016)/ (with various subfolders)

Any thoughts? (I have tried adding ‘TV/miscellaneous/’ as a separate source folder in Kodi by the way, in addition to the main ‘TV’ location, but still nothing)
