Hello:

I have a question about what I am calling 'sticky' sorts. I am using Calibre Portable version 5.23 and Windows 10, x64. Here's the process I am using:
1. I do a three level sort: Title, Author, then Genre. This, if I do it correctly, will put all of my books with no genre listed at the top. This indicates a new book for which I have not processed the metadata.
2. I select the top book.
3. I create a virtual library for the author of the book I have selected.
4. In the virtual library, which includes the new book(s) with no genre as well as any previously added books by the same author with included genre, I process the metadata for the book with the blank genre field, including adding information to the genre field.
5. I close the virtual library.
Here's where the change has occurred: Before, I would return to the library as sorted before the creation of the virtual library: Title, Author, Genre and I could select the top book as before. Now, all sorting is lost, and I have to click Title, Author, Genre again and then move the slider to the top of the list.

I have also noticed lately that after downloading a book's metadata, when changing the series name, upon completing the name change, the series number always changes immediately to 1.0, regardless of what it was before the change.

Has something changed in the way sorting is saved or have I changed a parameter that has changed the behaviour, or am I going nuts?
All suggestions would be most appreciated.
