I’d check whether the server is relevant for any otger fixlets that may shed some light.
In particular, there is a case where, if a system installs both the monthly Cumulative update and the Delta update without rebooting in between, the system may bluescreen at bootup. This has been occurring in Microsoft’s patches for almost two years now, with nothing on the MS side to block the installation.
The Bigfix team worked-around it by adding fixlet logic to ensure your system will only be relevant for the Delta update or the Cumulative update, but not both. If the system is current up to last month’s patch set, it will be relevant for only the new Delta update, and not for thr Cumulative. If your system is patched to a level older than last month’s, it will be relevant to only the Cumulative update.
Net result is you need both the Delta and Cumative rollups in your baseline. Your hosts will only download and execute the one relevant to them.
The easiest way to select patches for a new baseline is to view a Computer Group (which you could make for ‘All Computers’, and check the Applicable Fixlets and Tasks pane. That’ll show all the fixlets that can be applied to at least one member of the computer group.
(Edit: I haven’t checked this month specifically. I know Delta Updates are supposed to end this February but not sure whether this month saw the last delta, or the first month without a delta).
