Really pleased.
But I keep thinking should I get rid of any of these also...

ORIG AZW3 13
ORIG EPUB 1524
ORIG MOBI 73
PDF 14

Or leave well alone?
And if so, which ones do I really not want?
What do I type in to find them?
Is it the same as removing the Epub?

I value this forums help.
As you keep coming back to this I suspect you really do want to get rid of at least some of them.

I would delete the ORIG formats. The easiest way to do that is:
  1. Make a backup of your library in case something goes wrong.
  2. Open the "Formats" section of the tag browser (the pane on the left).

  3. Click the ORIG format you want to remove. A green plus sign will appear and all books having that format will be listed in the book list.

  4. Press CTRL-A to select all the books.
  5. Right click on the ORIG format and select "Remove ORIG ...". In this example it is "Remove the ORIGINAL_EPUB" from selected books".

  7. The format is deleted.

Note: while preparing this post I found a bug in the current calibre version where the tag browser formats list isn't cleaned up after deleting formats. I submitted a fix to Kovid for the next release. In the meantime you can "force" a cleanup by typing E (for edit metadata) then immediately pressing OK.

EDIT: The fix is now in calibre source and will be in the next release/preview.
