The mentioned properties are not part of SMW. Reassigning the bug to Drilldown
(but probably just to resolve as "WONTFIX" or "LATER").
The reason for the discrepancy is that SMW is aware of the Form namespace and
provides a special handling for it, including a datatype implementation that
allows users to omit the Form: prefix. This was done for reasons of peformance,
since SMW can thus store form data in its special properties table that is
faster to query (the form properties are queried very often since they are
relevant to display page actions). For drilldown filters, this special handling
is not needed. SMW's datatype managemen is currently not flexible enough to
allow extensions to add new datatypes that are not stored in the attributes
table (which would not be suitable for properties that refer to wiki pages).
Changing SMW's datatype system to allow more control of storage options
requires some more changes, so the matter can probably not be solved right now.
I have added a bug (Bug 21934) for SMW to implement this better
customisability.
