Grammaticality judgments misaligned using gb4e package

Question

I am writing my dissertation in Linguistics and use gb4e for the examples. When I try to add grammaticality judgments they appear indented, meaning aligned with the beginning of another example that is has no grammaticality judgment:

a. *The man is here who is carrying a large package.
b. A man is here who is carrying a large package.

The example sentences should all be aligned and any grammaticality judgments should appear on the left. What am I doing wrong?

\documentclass[a4paper,12pt]{book}

\usepackage{setspace}
\usepackage{mathptmx}
\usepackage[T1]{fontenc}
\usepackage{amsmath} 
\usepackage{cleveref}
\usepackage{gb4e}
\noautomath

\begin{document}

The example in \eqref{gs1} is ungrammatical. The example in \eqref{gs2} is fine.

\begin{exe}
\ex
\begin{xlist}
\ex[*]{The man is here who is carrying a large package.} \label{gs1}
\ex A man is here who is carrying a large package. \label{gs2}
\end{xlist}
\end{exe}

\end{document}

Answer 1

I'm certainly no expert, but after glancing at the documentation it appears you need

\ex[]{A man is here who is carrying a large package.}

for the second one.
