Why all initials are shown for names with a prefix in a citation?

Question

The citations in footnotes behave differently in my text, depending whether the author names contains a prefix, such as da or de.

For example, John Doe is rendered as Doe, Name of the book. as I expect. But Joao da Silva renders as J. d. Silva, Name of another work. On the bibliography the full name is printed correctly. What could be causing this difference?

Here's how I'm including biblatex:

\usepackage[
  backend=biber,
  style=abnt,
  citestyle=authortitle,
  autocite=footnote,
  citecounter=true,
  citetracker=true,
  useprefix=false,
  ittitles,
  scbib,
  noslsn
]{biblatex}

Example entry from .bib that renders as G. S. d. Sousa:

@book{gabriel-soares-tratado,
    author={Gabriel Soares de Sousa},
    title={Tratado Descritivo do Brasil em 1587},
    publisher = { Typographia de João Ignacio da Silva},
    location = { Rio de Janeiro },
    year = 1879
}
