Thread:Help talk:Inline queries/Query not working with particular redirect

I have a peculiar situation where querying (ask or show) using a redirect will not work, but the full page name will. So will not work, but  will ("DDCU" redirects to "DC to DC Converter Unit"). The same is the case with #ask. Furthermore, browsing for properties on the redirect page shows nothing for DDCU (says This page has no properties), but on other redirect pages it shows all the same properties as on the pages they redirect to. How do I fix this?
