WSUS - WHY oh why does the reporting suck?

So, we run WSUS on Server 2012 R2 for our environment.

In June, the 15th to be exact, I approved a rollup that contained a two specific patches.  When I search on those two specific patches, I can see the date I approved them since I use deadlines when I approve.  So, I know I approved the rollup and I have confirmed that the two specific KBs are in the rollup.

So, after I have run thru all of my patching, I run Computer Tabular Status for Approved Updates and it looks like all but one or two of my servers are all compliant.

Then I go back and I search on the two specific KBs and I do a detailed report and I find that over 100 servers do not have the patch in question.  

The patch was approved in the rollup.  The rollup was installed.  The Computer Tabular Status for Approved Updates report does not show any servers missing approved updates, yet my detailed report shows that the two specific KBs are needed on over 100 computers.  

This discrepancy in reporting is killing me!

So, if the KB is in the rollup, will it not show up in a report looking for the specific KB?  Or, another way to put it, will the specific KB only show in a report looking for that specific KB if the KB was installed standalone and not in a rollup?

I logged into some of the servers and I do not see the KB and that is matching up pretty well with the detailed report.

I'm just confused on why the reporting discrepancies.

Thanks
