Comment 3 for bug 2034999

This will be because of some customization in your book details CSS
file. Go to Preferences->Look & feel->Book details and restore the text
styling section to default. The default is:

body, td {
    background-color: transparent;
}

body.horizontal table td.title { white-space: nowrap }

a {
    text-decoration: none;
}

.comments {
    margin-top: 0;
    padding-top: 0;
    text-indent: 0
}

.comments-heading {
    font-size: larger;
    font-weight: bold
}

table.fields {
    margin-bottom: 0;
    padding-bottom: 0;
}

table.fields td {
    vertical-align: top
}

table.fields td.title {
    font-weight: normal;
    font-style: italic;
    color: palette(placeholder-text);
    text-align: right;
}

.series_name {
    font-style: italic
}
