"booktitle" and "chaptertitle" strings are empty

The booktitle and chaptertitle strings do not work. There is no book title nor chapter title in the top margin. Of course, the book has at least a title in the metadata (I don't know where chapter titles are taken from). Conversely, the counter(page) and counter(pages) do work. Here is the CSS file:

/*
@font-face {
  font-family: serif;
  src: local("Droid Serif")
}
*/

@page {
  size: 210mm 297mm;
  margin: 2.5cm !important;
  @top-left {
    font-size: 50%;
    font-style: italic;
    border-bottom: solid thin black;
    margin-bottom: 1mm;
    content: string(booktitle);
  }
  @top-center {
    font-size: 50%;
    font-style: italic;
    border-bottom: solid thin black;
    margin-bottom: 1mm;
    content: string(chaptertitle);
  }
  @top-right {
    font-size: 50%;
    border-bottom: solid thin black;
    margin-bottom: 1mm;
    content: counter(page) "/" counter(pages);
  }
}

@page:first {
  margin: 1mm 1mm 1mm 1mm;
  @top-left {
    border-width: 0;
    margin: 0;
    content: normal;
  }
  @top-center {
    border-width: 0;
    margin: 0;
    content: normal;
  }
  @top-right {
    border-width: 0;
    margin: 0;
    content: normal;
  }
}

body {
  font-size: 10pt;
  font-family: serif;
  text-align: justify;
  prince-image-resolution: 166dpi;
  hyphens: auto;
  string-set: booktitle "@{@{title}@}@"
  string-set: author "@{@{author}@}@"
}

Images are too small

Prince conversion gets images too small, as you can see from this screenshot:

Instead, stock PDF conversion scales the images much better

This is a serious problem because some badly tailored ebooks put text into images which are unreadable if they are too small. Here is an example:

Prince (unreadable):

Stock PDF conversion (more readable):

Unless I am missing some Prince option that manages this

Configuration dialog goes off screen (buttons unclickable)

As you can see from the screenshot, the configuration dialog has borders that goes off screen.
The "OK" button is not clickable.
Also, the dialog is not resizable (going with the mouse on the border and trying to reset it does not work as expected)
