I have two identical documents in our DEV and PROD tiers. When a user views a document searched up via Weblink in the DEV tier the Details pane contains three Entry Properties: Modified, Created & Path.

When a user searches up the same document in the PROD tier only two Entry Properties are displayed: Modified and Created.

What controls which Entry Properties are displayed? I've set up a Search Form in each tier for the user to use and as far as I can tell the forms are set up identically. Is there some overriding site configuration I've missed?

I don't see how it could be a permissions issue. I know that can be an issue with Fields but what would control permissions on viewing Entry Properties? They seem to be an inherent property of the entry. If you can view the entry then it seems like you could view the properties.
