A rollup includes all updates for a specific period. In this case, the KB4074598 rollup includes all updates for the month, including the KB4074587 update, which is the one missing from your WIndows update list. The MBSA utility doesn't take superseded updates into account, and the second update in your top picture is superseded by the first listed update (Rollups include all updates, so installing the update and the rollup is redundant).

The Microsoft Update list should include updates for Microsoft SQL Server, and MBSA will scan for missing SQL server security updates as well. Note, here, that SQL server security updates are less common, and SQL server generally follows a quarterly rollup schedule, rather than issuing individual updates. This is because SQL server requires more availability than Windows Server, and changes to SQL server will always require SQL services to shut down.
