箭消失

由于某种原因，S/V/NP 和 V'V 之间的箭头没有画出来。我不知道为什么...

\documentclass{article}



\usepackage{tikz-qtree}
\tikzset{every roof node/.append style={inner sep=0.1pt,text height=2ex,text depth=0.3ex}}

\usetikzlibrary{tikzmark}

\newcommand{\sliste}[1]{%
\mbox{%
$\left\langle\mbox{\scshape #1}\right\rangle$}%
}


\begin{document}

\begin{tikzpicture}[
level 1+/.style={level distance=3\baselineskip},
frontier/.style={distance from root=15\baselineskip},
connect/.style={semithick,<->,color=green}]
\Tree[.S
        [.\node (NP) {NP}; bogen ]
        [.\node (S/NP) {S/NP};
          [.{V \sliste{ S//V }} 
            [.V læser$_k$ ] ]
           [.\node (S//V/NP) {S/V/NP};
             [.NP Jens ]
             [.\node (V/V) {V$'$V};
               [.{V//V}  trace ]
               [.\node (NP/NP) {NP/NP}; trace ] ] ] ] ] ]
\draw[connect] (NP/NP.north east) [bend right] to (V/V.south east);
\draw[connect] (V/V.north east) [bend right] (S//V/NP.south east);
\draw[connect] (S//V/NP.north east) [bend right] to (S/NP.east);
\draw[connect] (S/NP.north east) [bend right] to (NP);
\end{tikzpicture}


\end{document}

to节点(V/V.north east)之间缺失(S//V/NP.south east)

\draw[connect] (V/V.north east) [bend right] to (S//V/NP.south east);

您认为更换一些锚点以获得新的箭头怎么样，如下所示？

在此处输入图片描述

\draw[connect] (NP/NP.north east)   [bend right] to (V/V.east);
\draw[connect] (V/V.north east)     [bend right]    (S//V/NP.east);
\draw[connect] (S//V/NP.north east) [bend right] to (S/NP.east);
\draw[connect] (S/NP.north west)    [bend right] to (NP);
