type="pagelist" not showing dropdown of pages

I have this code working on one site, copied into my current project and it shows text field rather than the pagelist drop down. Yes, I do have other pages on the site.

<perch:if exists="ServicepgLink"><a href="<perch:content id="ServicepgLink" type="pagelist" label="ServicePg Link" required="true" output="urlify" />"></perch:if>
