For some reason, the points DO appear in the parts and subparts but it doesn't appear in the main questions in this document. I tried removing the 3 lines between the 2 ** too in case they were causing it. Nothing helped.

\begin{questions}
\question[10]
Find the distance
\end{questions}
\end{document}
If I have parts in the question, they do appear in the right margin like [10] as desired...
I gave \pointpoints{ mark}{ marks}
but I don't get "marks" after the parts and one question is messing up.
