Monthly Rollups tend to be cumulative, meaning that the Monthly Rollup from March, for instance, will be overwritten by the Preview or complete Monthly Rollup of April within the WMI of your Windows assets. This process is controlled by Microsoft, and unfortunately, Lansweeper cannot change it.
This means that any vulnerability reports or older Patch Tuesday reports become outdated very quickly, and as such, will start to report false positives.
Unfortunately, Lansweeper does not have the resources to keep the vulnerability reports up to date, so we would recommend using the latest Patch Tuesday report that is available: https://www.lansweeper.com/resources/report/?fwp_report_category=patch-tuesday
