Why is the total for gradingrange section1 wrong?

Question

\documentclass[a4paper,12pt,addpoints]{exam} 

\begin{document}
    \begin{questions}
        \begingradingrange{section1}
            \question[10] Here is my first question worth 10 points\\
            The number of points in section one are \pointsinrange{section1}
        \endgradingrange{section1}
    \end{questions}
   
    \begin{questions}
        \begingradingrange{section2}
            \question[25]% 
                Here is my second question worth 25
        \endgradingrange{section2}
    \end{questions}
\end{document}

Output

1. (10 points) Here is my first question worth 10 points The number of points in section one are 25
2. (25 points) Here is my second question worth 25

Question why does \pointsinrange{section1} return 25 rather than 10?
