Glossary entry page numbers reference glossary page [closed]

Question

I've set up a glossary following this guide, but all the entries in my glossary contain page number references to the glossary page - from within the glossary page. I don't have any instances of \gls{} or similar commands within the glossary. My structure is like this:

\usepackage[xindy,toc,acronym]{glossaries}
\makeglossaries

\include{glossary_entries}

% my document body

\appendix
\input{glossary}

glossary_entries.tex contains entries such as:

\newacronym{ETA}{ETA}{Estimated Time of Arrival}
\newglossaryentry{route}{name=Route,description={A set of Waypoints in three-dimentional space}}

All the entries refer to page 34 (the glossary) as well as their correct instances.
