How to remove the word "ïmmediate" when using \maketitle

Question

When I use the latex syntax \maketitle to write the title, I get a word "immediate" written below it. I googled for an alternative and found something called \titlepage. Now when I use titlepage, it allocates an entire page for the title. And I don't want that. I just want the word "Immediate" to not appear. How can I do that? Any alternatives you know of?

\documentclass[11pt]{article}
\usepackage{authblk}
\begin{document}
\nocite{*}
\title{this is the title}
\maketitle
\end{document}

Answer 1

After removing packages and code, which do not make immediate disappear, the following remains:

\documentclass[11pt]{article}
\usepackage{authblk}
\begin{document}
\title{this is the title}
\maketitle
\end{document}

With the following warning:

LaTeX Warning: No \author given.

Also, let us make authorblk/\maketitle happy:

\documentclass[11pt]{article}
\usepackage{authblk}
\begin{document}
\title{this is the title}
\author{}
\maketitle
\end{document}

immediate and the warning are now gone.

Nevertheless, the word immediate should not appear, if \author is not given. It's part of the code, which prints the warning message. A bug report can be made for authblk (but I do not know, whether it is maintained, the last version is from 2001). However, why is a package for author affiliations is loaded, if there aren't any authors?
