Update view not working anymore

The only thing this server syncs from is Microsoft Update

I think I'm being confused by this statement. If the only thing the server syncs from is Microsoft Update, then why the need for a filtered view of updates that basically is designed to show ALL updates? (Btw, you can quick view this information by enabling the Source column in the All Updates view and filtering on the value "MicrosoftUpdate".)

there are 6 patches with 3 KB numbers: KB2970228 KB2975331 KB2975719

There are two sets of updates for this collection. One that is Expired; One that is current. Here's a view from my All Updates listing:

The *expired* updates are automatically filtered from the custom view with the filter set. (They would not be filtered if using the All Updates view and filtering on the Source column as described previously. Here's a view from your custom view definition that I recreated on my system:

If you have *NO* updates in your custom view, then that begs the question of where are the 9/2/2014 versions of those updates. Possibly, since you posted only an hour ago, the updates released yesterday had not yet been synchronized to your WSUS server. Or possibly your Patch Manager console needs a refresh?

Argh. User error. I thought I had triple checked everything, but I had a stray filter set because I was trying to track down a few computers that hadn't been on in a while. Nothing to see here!

These are not the droids you are looking for...
