Dewey Decimal Code = DDC

I think I have made a hierarchical structure, following "Managing subgroups of books, for example “genre”", but using Dewey hundreds, then Dewey tens and occasionally Dewey single digits. So 500.550.551 is where Global Warming books go. And 400.490 is for Egyptian Hieroglyphics.

This all works nicely, with access to the DDC subgroups in the left pane below the tags, or in a column in the books display area.

But.
When I try to have two or more Dewey codes for a single book then the codes are not treated separately but instead all just put in a continual sequence.
So 100, 200 is just treated as being a special category of the 100 subgroup. And the book doesn't show with the other DDC 200 books.

The tutorial says that multiple genres are possible for a single book. Is the problem that I am using numbers rather than letters for places in the hierarchy?

It looks to me like I am not using the correct separator between the codes. I have tried commas and spaces so far.

Any help appreciated.
