Silverlight 4 install patched but still shows out of compliance

I have some machines with Silverlight 4 and they have received the patch from MS12-034 but still show as missing a critical update.

• Installed Updates report shows the Silverlight 4 update is installed
• Not Installed Updates report show the Silverlight 5 update is missing
• Software inventory of the computer confirms only Silverlight 4 is installed
• WSUS does NOT show this as a required update for these computers.

Why is Altiris flagging the Silverlight 5 update a required update when Silverlight 5 isn't installed?

Thanks in advance for your help.
