¿Cómo reducir el espacio en el ejemplo de brillo de gb4e?

Question

Estoy escribiendo un paquete linguistics papery lo uso gb4e. Para la siguiente oración, no sé cómo reducir el espacio entre las dos oraciones de ejemplo consecutivas. Cualquier otra solución además de usar \vspace{}.

Aquí está el código:

\documentclass[12pt]{report}
\usepackage{url}
\usepackage[numbers,sort]{natbib}
\usepackage[dvips]{graphicx}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{xcolor}
\usepackage{tipa}  
\usepackage{tikz} 
\usepackage{tikz-qtree} 
\usepackage{gb4e} 


\begin{document}

\begin{exe}
\ex
\label{7}
\begin{xlist}
\ex 
\label{7a}
\gll Ali [ men ket-t-im ] di-d-i.\\
Ali [ \textsc{1sg.nom} leave-\textsc{past-1sg} ] say-\textsc{past-3sg}\\
\textsc{Shifted}: \ding{51} `Ali_{i} said that he_{i} left.'
\vspace{-0.3cm}
     
\textsc{Nonshifted}: \ding{55} `Ali_{i} said that I_{speaker} left.'\\

\ex 
\label{7b}
\gll Ali [ meni ket-t-i ] di-d-i.\\
Ali [ \textsc{1sg.acc} leave-\textsc{past-3sg} ] say-\textsc{past-3sg}\\
\textsc{Shifted}: \ding{55} `Ali_{i} said that he_{i} left.'
\vspace{-0.3cm}
     
\textsc{Nonshifted}: \ding{51} `Ali_{i} said that I_{speaker} left.'\\
    \end{xlist}
\end{exe}

\end{document}
