calibre 0.9: strange display behavior for formats
I had quality problems with a few books converted a while back from mobi to epub, so suppressed the epub versions. I was surprised to see that the column "formats" (I have the French version) went empty for those books, while the books' metadatas to the right of the screen said correctly that it still had the mobi version.
I then reconverted from mobi to epub, and the column now has mobi, but lacks the epub which appears correctly in the book's metadata.
I have calibre 0.9 64 bits and a Windows 7 PC.
