抱歉，这个问题可能比较基础。我使用模板制作了一张海报，并在各个区块内创建了项目符号列表。在其中一个区块内，项目符号位于区块本身之外，而在所有其他区块中，项目符号都在区块内部。
我和 writelatex 的一名员工仔细查看了代码，但不幸的是，我们俩都无法找出问题所在。代码与其他任何块似乎没有任何区别。
这是代码；

\begin{block}{Introduction}
\begin{itemize}
\item The manifestation of a broad and significant police reform agenda (see Home Office, 2010) has both directly and indirectly presented opportunity for police organisations and education providers to define and design supplementary and additional routes in training and entry into the police service. One example of the recent diversification of pre-entry programmes is the development of the FdA Policing programme at Bucks New University, which has been designed in partnership with Thames Valley Police (TVP) to serve as a form of pre-entry into the service.
\item This poster presents the aims and initial findings of an associated project, designed as an exploratory and descriptive analysis of the candidate response to the programme. Specifically, the poster presents selected findings from a monitoring and mapping exercise of a specific candidate cohort.
\end{itemize}
