调整图后的垂直间距 kaobook

Question

我的代码如下：

\documentclass[%
    fontsize=10pt, %
    twoside=true, %
    open=any, %
    chapterentrydots=true, %
    numbers=noenddot %
]{kaobook}

\usepackage{lipsum}

\begin{document}

\lipsum[1-2]

\begin{figure*}[t!]
\captionsetup{width=0.95\linewidth}
\centerline{\includegraphics[width=0.95\linewidth]{example-image}}
\caption{This is for test. This is for test. This is for test. This is for test. This is for test. This is for test. This is for test. This is for test. This is for test. This is for test. This is for test. This is for test. This is for test. This is for test. This is for test. This is for test. This is for test. This is for test. }
\vspace{-20pt}
\end{figure*}

\lipsum[3-4]

\lipsum[5-6]

\end{document}

这可行，但vertical space adjustment之后不工作figure，但标题垂直凸起，这不应该发生，请参阅下面显示的图像：

如何在figure环境之后调整垂直空间（减少/增加）？

我对此很陌生kaobook，所以如果我的问题很愚蠢，请原谅我......
