I can't read the last screenshot properly, but it is the Metadata Plugboard screen. Based in the other pictures, I think you have the plugboard defined wrong. It looks like you have:
Code:
<title> - <number> - <series>
But, it should be:
Code:
{title} - {series_index} - {series}
Using the details from the second picture, that would set the title to:
Code:
Gud- 32 -Taenkepauser
I find that a strange choice for the title as I can't think of what benefit it gives on a Kobo ereader. A more common choice is:
Code:
{series}{series_index:0>2s| - | - }{title}
Which would give:
Code:
Taenkepauser 32 - Gud
That has the advantage that a title sort puts the books in the correct series order.
