Aura Books not listed by title but just " - - "

Hi guys

I use Calibre to make sure that the metadata for my ebooks are fine and then sideload books to my kobo aura.

For some reason the last two books I've sideloaded appear "funny" on my bookshelf. Can somebody explain to me whats going on or more importantly how to fix it.

As you can see on the picture below the two books are listed as <title> - <number> - <series> instead of their actual title. Both of the books are in a collection called "Tænkepauser" (Danish word) - but that is only displayed on one of them.

If you check the metadata everything looks to be ok:

Without fully understanding it I use the following plugboard - which used to work out fine for me:

I hope somebody can help me make my books appear with the rigth title and collection.

Thanks!
