Omnibus troubles

Hello, I have a copy of a science fiction omnibus that contains 3 novels, each by a different author. The work-to-work relationship thing looks right, but when I go to the authors' pages, their individual work does not show as existing in my collection.

My book:
- Science Fiction Special (17)

Contains:
- Dying Inside, by Robert Silverberg
- Flight from Time One, by Deane Romano
- The Darkness on Diamondia, by A. E. van Vogt

Can anyone let me know if there's something wrong with the work-to-work relationship, or if I've entered something wrong when adding the book. I'd ideally like to have the individual works ticked as being in my collection even though I don't own them as separate books. I might buy another copy of the same work by accident, if I don't realise I have it already. Does that make sense?

Hope you can help, and many thanks in advance.

Nothing's wrong; that's just how the work-to-work relationship works (at least for now). At some point in the future it might do what you want, but we don't really know for sure. What some people do is add "phantom" copies of the individual works that they own in omnibus form, maybe in a separate Collection, so that you know you don't actually have a separately-bound copy of, say, Dying Inside.

Thank you :)
