Maybe the first time you sent the book you where using an older version of Calibre and the plugin, and the plug-in didn't identified the cover in a way that Kobo could recognize the cover.
When you deleted the book from Kobo, the data related to the book, including the cover, was deleted from the database, and the next time you sent the book you were using a newer version of Calibre and the plug-in, and the cover was correctly identified.
I manually edit the Metadata in my books when I add them to Calibre to ensure that things like the cover are correctly identified, but I have found that some older books that I bought before having my first Kobo don't show the cover. These books don't have a specific property for the cover in the Metadata, I began adding it because of the cover problem, but I don't know if it's still necessary, maybe newer versions of Calibre and the plug-in have solved this problem, I haven't tried to add an old book for some time.

Sorry, I update the books on my reader frequently als I never have >20 on it (I don't understand why people wants to have hundreds of already read books on their device) and every book I add to calibre, has correct metadata and covers. ( I check them all when adding to Calibre,then update metadata for my catalog)
It is not a structural error in the book, first I check them with flightcrew, and if I add books to my reader,and re-add them,it is with the same version of calibre.
I don't add old books to the reader,simply because I already read it, but I tried it with 2 more then 6 year old books and they are there perfectly with cover,so it has nothing to do with old books.
If it was the book, it would happen again with the same book over and over again,also on the second reader but it doesn't.
I only support the message of molier,that it happens to me also that covers are not displayed,in random order,on random devices with both kepub and epubs,new or old.
Every book in Calibre has it's own cover file and it's own metadata file.
Database check for error by Kobobooks Utility plugin says nothing is wrong.
It doesn't bother me, because I use the sleepcover so normally I don't see the covers in sleepmodus at all.
When select it from the library list I can see there is no cover displayed,but I don't care for that to because the thumbnails are so small that i can't read them well.
The book not displayed on the homescreen doesn't bother me also because I read from sleep and don't use the homescreen at all.
I never convert ebooks,it is just import,edit metadata,send it to the device.
I wish it was due to old books,because then I could reproduce it.
