# achemso package: TOC entry behaves strangely

I am trying to write a manuscript for J. Phys. Chem. Lett. using the achemso package. But I am encountering a strange problem with the TOC entry (defined by \begin{tocentry} ... \end{tocentry}) when I use the journal=jpclcd class option. With journal=jacsat, the TOC entry gets printed in a separate page at the very end as documented. But if I use journal=jpclcd the TOC entry is printed just after the Abstract.

Here is a minimum working example:

\documentclass[journal=jpclcd,manuscript=letter,layout=twocolumn]{achemso}

\title{This is my title}
\author{Unknown Author}
\affiliation{Unknown University, Unknown Town}

\begin{tocentry}
This box and the associated title will always be printed on a separate page at the end of the document.
\end{tocentry}

\begin{document}

\begin{abstract}
This is my abstract.
\end{abstract}

\end{document}


Also, not using the tocentry section leads to the following very confusing error:

! Undefined control sequence.
<argument> ...@tocentry@width {\acs@tocentry@text
}\end {minipage}
l.132 \end{abstract}


Here is a minimum working example to reproduce this error:

\documentclass[journal=jpclcd,manuscript=letter,layout=twocolumn]{achemso}

\title{This is my title}
\author{Unknown Author}
\affiliation{Unknown University, Unknown Town}

\begin{document}

\begin{abstract}
This is my abstract.
\end{abstract}

\end{document}


Any suggestion regarding how to workaround this issue for journal=jpclcd would be much appreciated.
